Bought BF2042 off Epic games store. Been trying to get it to work with Steam.

Please help

Yeah I know "add non-steam game to library" but Steam doesn't show me as playing and the Steam overlay doesn't work. I tried all the exe's in the BF2042 directory. BF2042_launcher.exe works momentarily but once that closes out and the actual BF2042.exe starts up it stops working.
