I really like how Steam Game Recording works in general, but it's audio implementation is awful. It frequently forgets that Discord exists and often doesn't record it, even when it's enabled and you have no ability to mix audio levels. Through my BEACN Mix Create or through other tools like VoiceMeeter, people have the ability to create custom outputs that mix multiple other outputs together and level them independently. If Steam would just allow me to say "do all recordings from this output", it would solve everything. Several other applications do this and it would be a game changing feature, at least if they can't get it to reliably detect Discord.

The feature doesn't seem to have been updated since exiting beta (I mean heck, this still doesn't have an official Steam forums and you have to join a group still labelled beta to discuss it), but I hope someone at Valve is still maintaining it and could add this in because otherwise, it's a great feature that I would use all the time, instead of pulling my hair out trying to find an alternative that doesn't have issues of its own. Cheers.
