How to make Automator auto press a key on a different application?

MacBook Pro macOS Sequoia 15. How do you make Automator auto press a key? I have tried using “Watch Me Do” pressed the desired key set it on pause and loop but when i run the file it doesn’t register the key press in a game or application. When I used the same “Watch Me Do” to auto press my mouse it works but not with a key it doesn’t matter if it’s a letter or number it won’t register does anyone have a clue how to make it register?
