This method is here to make it easier to use new API methods that are not yet supported
by this library.
Hint:
Since PTB does not know which arguments are passed to this method, some caution is
necessary in terms of PTBs utility functionalities. In particular
* passing objects of any class defined in the :mod:`telegram` module is supported
* when uploading files, a :class:`telegram.InputFile` must be passed as the value for
the corresponding argument. Passing a file path or file-like object will not work.
File paths will work only in combination with :paramref:`~Bot.local_mode`.
* when uploading files, PTB can still correctly determine that
a special write timeout value should be used instead of the default
:paramref:`telegram.request.HTTPXRequest.write_timeout`.
* insertion of default values specified via :class:`telegram.ext.Defaults` will not
work (only relevant for :class:`telegram.ext.ExtBot`).
* The only exception is :class:`telegram.ext.Defaults.tzinfo`, which will be correctly
applied to :class:`datetime.datetime` objects.
