Uninstall Early Access after reinstalling Windows

Hey all, I had to reinstall windows and also a new epic laucher. I tried to reintegrate my old early access unreal 5 engine, but when I hit the “+” the UE5_5.0EA is not available anymore (5.0.3 is the oldest). As it needs a lot of space - how can I uninstall it completely without just removing the directory?

Thanks in advance!
