Hope you can help

I've recently set up TP Deco M4. I've added child filters and they've been working fine without issue.

However today when she was on a zoom call (for Brownies) the camera wouldn't switch on. I've temporarily removed all filters and it's working again.

I just wondered which of the filters blocked this (I'm guessing it's Online communications) and if there was a way to still have it blocked but allowed zoom camera access on there.
