I know a few methods to use Screenshot, but I'm tried of using screenshot haha, it creates too many problems for me.

I tried using "ActionChains" but once the right click menu pops up it won't send any input to there, probably because it's a windows GUI and not part of chrome (using chrome driver / selenium by the way)
