Stupid Rookie question

Please forgive this seemingly ridiculous question…I just downloaded the wemod app…got it to use as a trainer for Metro Exodus…all seems to be pretty straightforward, except once I start to Play the game, I can’t get to the wemod app to do what I need to do there…if any of that makes any sense (lol)

How bout alt-tab back to wemod ?

it not really that hard, i play on windows 10 so i either use the Windows button or pres ESC + CTRL to get to Wemod, or just play the game windowed
