docs: Use this method to get information about a user.
          You can retrieve up to 200 users at once.
  
          Args:
              user_ids (``iterable``):
                  A list of User identifiers (id or username) or a single user id/username.
                  For a contact that exists in your Telegram address book you can use his phone number (str).
                  Iterators and Generators are also accepted.
  
          Returns:
              On success and in case *user_ids* was an iterable, the returned value will be a list of the requested
              :obj:`Users <User>` even if a list contains just one element, otherwise if
              *user_ids* was an integer or string, the single requested :obj:`User` is returned.
  
          Raises:
              :class:`RPCError <pyrogram.RPCError>` in case of a Telegram RPC error.
