Using Samsung Live Captions with Zello app

I have a question, I use Zello app for work (Company work app). I wanted to use my Live Captions that is built in my S21 FE phone to caption the calls in Zello, but for some reason it won’t capture the audio in Zello. I’m wondering if it’s due to the security in the Zello app. Does anyone here have any experiences with this?
