    The function creates a ``ParticleList``, selecting particles according to the chosen ``working_point``,
    and decorates each candidate in the list with the nominal Data/MC :math:`\\ell` ID efficiency and
    :math:`\\pi,K` fake rate correction factors and their stat, syst uncertainty, reading the info
    from the Conditions Database (CDB) according to the chosen input global tag (GT).
 
    .. note::
        Particles will **not** be selected if they are outside the Data/MC *efficiency* corrections' phase space coverage        for the given working point.
        In fact, the threshold value for the PID cut in such cases is set to NaN.
 
    .. warning::
        At the moment, the only supported *binary* lepton identification is against the **pion** hypothesis.
        This implies that, if binary classification is chosen, only :math:`\\pi` fake rate corrections will be added to the
        resulting particle list.
 
    Parameters:
        pdgId (int): the lepton pdg code.
        working_point (str): name of the chosen working point that defines the content of the list. Choose among the above values.
        method (str): the PID method: 'likelihood' or 'bdt'.
        classification (str): the type of classifier: 'binary' (one-vs-pion) or 'global' (one-vs-all).
        lid_weights_gt (str): the name identifier of the global tag with the recommended Data/MC correction weights.

                                  for info about the recommended global tags.
 
        release (Optional[int]): the major release number of the data and MC campaigns considered.
                                 If specified, it ensures the correct :math:`\\ell` ID variables are used.

                                     for info about lepton identification variables and campaigns.
 
        channel_eff (Optional[str]): the channel used to derive the :math:`\\ell` ID efficiency corrections.
                                     By default, 'combination' is set, meaning they are obtained by combining results
                                     of several hadronic and low multiplicity channels, wherever they overlap.

                                         for other possible choices (if any).
 
        channel_misid_pi (Optional[str]): the channel used to derive the :math:`\\pi` fake rate corrections.
        channel_misid_K (Optional[str]): the channel used to derive the :math:`K` fake rate corrections.
        inputListName (Optional[str]): the name of a pre-existing ``ParticleList`` object (defined as a full ``decayString``,
                                       e.g. 'e-:my_input_electrons') of which the standard lepton list will be a subset.
                                       For instance, users might want to apply a Bremsstrahlung correction to electrons first,
                                       which modifies their 4-momentum, and only later define the subset passing the PID selection,
                                       including the appropriate PID weights and uncertainties (which are :math:`p`-dependent).
                                       By default, the standard lepton list is created from all ``Track`` objects in the event.
 
                                       .. warning::
                                           Do **not** apply any PID selection on the input list, otherwise results could be biased.
 
        outputListLabel (Optional[str]): the name of the output lepton list label, i.e.,
                                         the string that follows the particle identifier ('e-:', 'mu-:').
                                         By default, it is assigned as:
                                         ``'{method}_{classification}_{working_point}'``.
 
        trainingModeMulticlass (Optional[``Belle2.ChargedPidMVAWeights.ChargedPidMVATrainingMode``]): enum identifier
                               of the multi-class (global PID) training mode.
                               See `modularAnalysis.applyChargedPidMVA` docs for available options.
        trainingModeBinary (Optional[``Belle2.ChargedPidMVAWeights.ChargedPidMVATrainingMode``]): enum identifier
                           of the classification (binary PID) training mode.
                           See `modularAnalysis.applyChargedPidMVA` docs for available options.
        path (basf2.Path): modules are added to this path.
