          Args:
              commands (``str`` | ``list``):
                  The command or list of commands as string the filter should look for.
                  Examples: "start", ["start", "help", "settings"]. When a message text containing
                  a command arrives, the command itself and its arguments will be stored in the *command*
                  field of the :class:`Message <pyrogram.Message>`.
  
              prefix (``str`` | ``list``, *optional*):
                  A prefix or a list of prefixes as string the filter should look for.
                  Defaults to "/" (slash). Examples: ".", "!", ["/", "!", "."].
                  Can be None or "" (empty string) to allow commands with no prefix at all.
  
              separator (``str``, *optional*):
                  The command arguments separator. Defaults to " " (white space).
                  Examples: /start first second, /start-first-second, /start.first.second.
  
              case_sensitive (``bool``, *optional*):
                  Pass True if you want your command(s) to be case sensitive. Defaults to False.
                  Examples: when True, command="Start" would trigger /Start but not /start.
