Allowing the user to prevent Discord from seeing a certain process as a game and showing 'Playing <process_name>'

The reason I am asking this is that, on my Discord version, which is for Arch Linux, it picks up Proton's processes (Proton is like Wine but comes with Steam), for example pressure-vessel-launch as seen in the screenshot, and is showing as a game, even though it is not. I wanted to prevent discord from showing this as a game, but I could not find an option to prevent it, so it would be useful to add that option. (No, the files app which looks like a filing cabinet is not open, it is pinned to taskbar.)
