Application help- display app controls when not in focus

Hi I am new to BetterTouchTool, so bear with me. I am just trying to keep a certain applications app controls in my Touch Bar at all times even when I am not in focus with that app. The app controls that I always want displayed in my Touch Bar is TouchBarPets, it’s basically tamagotchi where you raise pets in your touch bar. Currently, the touchbarpets only displays in my touchbar when I am in focus on the app but I want it to always display, even when I open a different app like safari. Can someone give me detailed instructions on how to do this? I don’t know how to work BetterTouchTools and is confusing to me. Thanks
