Heroic Cannot Launch Games

I just downloaded Heroic (LinuxMint, using GOG and EGS) and I can't seem to get anything to launch once it downloads (Tomb Raider: Anniversary, Tomb Raider: Underworld, 20XX, Shadowrun Returns (Linux version). Not sure what's wrong and very new to Linux. I've tried resetting the launcher and installing MangoHUD but nothing works.
