Disable sleep button of my keyboard in Gnome DE

How can i disable sleep button of my keyboard in Gnome DE in manjaro OS?

The way I know ~ You can edit the logind.conf file to alter the action of sleep/shutdown buttons & close lid.

sudo nano /etc/systemd/logind.conf

Look for the line below, duplicate it, uncomment with a new behaviour.

#HandleSuspendKey=suspend
HandleSuspendKey=ignore

& then restart & test it.
