"Please use Firefox or Chrome" When using firefox or chromium

When I open the mimic recording studio in my browser it’s telling me to use firefox or chromium. When attempting to record anyways the program crashes. Same result on both firefox and a chromium-based browser, using manjaro 20.2. The microphone works fine on other software, so I’m assuming the issue isn’t in my OS. Any help would be appreciated.

Seems like it’s not finding audio recording api?
