Using Quicktime + Blackhole

Hey guys is it possible to record zoom meeting with quicktime and blackhole (i was using blackhole 2 ch)? Because it used to work before but now i can't record zoom meeting audio at all. They just didn't catch it, but when i try to play youtube on the background they do catch the sound. Can anyone help me with this, cause not everyone can record the meeting using the zoom app only (there's a limitation)

anyway sorry if my english wasn't too good, but i really need help
