• if it does not show effect when you click that means you should change the input file by using -i flag. this is becouse the input file for your keyboard file might be differant so check the event file in your /dev/input/eventX' where X might be any number. for example if you want to check /dev/input/event2then runcat /dev/input/event2` then click any key on the keyboard if there is an output it means that this is the keyboard input file else try another file.
• if when you use cat /dev/input/event0 you get authentication failed or something like that. then you have two options. first: run the program as root (not recommended) second: add yourself to the input group
