what is the correct keywords for mouse_modifier?

[txl263]

environment:

macOS 13.7.1 22H221 x86_64
yabai-v7.1.5
Poker keyboard with USB

This config not work on my computer. So is it a configuration conflict? Why?

yabai -m config mouse_modifier               fn
yabai -m config mouse_action1                move
yabai -m config mouse_action2                resize

I can changed it to shift and it worked. But how to change it to anohter key like Command or Control?
It always said unknown value 'control' given to command 'mouse_modifier' for domain 'config' So, what is the correct keywords？

And another problem.
One of the rules in the config file is yabai -m rule --add app="^Telegram$" manage=off did not work unless execute yabai -m rule --apply in terminal. I already have yabai -m rule --apply in config file.

I am aware of these possible values for the mouse_modifier config:

ctrl, alt, cmd, shift, fn
