How/where would I find a particular console command in the game files?

With this part I'm having a little issue:

@sims4.commands.Command('h', command_type=sims4.commands.CommandType.Live)
def headline(enable:bool=None, _connection=None):

	if enable is not None:
		if enable:
			command = 'headlineeffects on'
			sims4.commands.client_cheat(command, _connection)
		else:
			command = 'headlineeffects off'	
			sims4.commands.client_cheat(command, _connection)
	else:
		output("You need to turn this on or off with 't', 'true', 'on', '1', 'yes', 'y', 'enable' or 'f', 'false', 'off', '0', 'no', 'n', 'disable'")

The actual commands are working as expected (like with "h 1" or "h off" or whatever), but when I only type "h" I don't get the expected output .. and I don't understand why not. (The reason I want that is to prevent myself from forgetting that this is not a toggle)

?

lastexception.txt is not complaining about me (as it did yesterday, about my untidy whitespaces).

(I also have a feeling that the inner if is probably unnecessary as I can probably pass the bool directly somehow, I only don't want to change too many things at once)
