THX Spatial audio not finding supported games

Hi, I recently bought THX spatial and it works fine for normal sound etc, but it also has an option for supported games to set extra's, I have some of those games but it doesnt add them to the list (It added 2 games, Discord and my webbrowser but none of the others) I've been looking to add them manualy but that seems not an option, also looked online but am not gettig any results, hope anyone can help me out with this.
