I really like this plugin! At first, I thought there was something wrong with how I installed it because I followed all the steps thoroughly but it didn't work. But I noticed that some of my installed plugins weren't working as well, so I tried downgrading my OBS to version 27, and it's working perfectly!
OBS seems to have broken a lot of plugins since the release of version 28. So if anyone's having plugin issues, try downgrading it to version 27 (make sure to backup Profiles, Scene Collections, and the like).
