How to make Livesplit display in a fullscreen game?

I went on to try and find out myself but I think you can't do that. Livesplit would show in OBS but you can't see it while you're playing yourself. You would have to disable fullscreen and lower the resolution a bit and then It should work. In OBS you can still configure it, so it looks like its all on fullscreen in the recording.. thats how I done it atleast. Maybe someone else knows how but that was my way.

very thankful
