have you tried flatseal? The Flatpak manager. If I recall you are able to control flatpak and alter some of its access. Maybe? I never had that issue. Don't use Zorin. Zorin gatekeeps their features behind a pay wall. What is worse, after you pay, you have to buy it again if they upgrade versions.
I'd rather spend a few minutes with a basic linux and get all that without the paywall. I am not going to reward them for gatekeeping. In the past I tried their free version and thought. Hey I will just install it myself. Not a problem. Except it isn't part of the distro list (forget the name now.) . I'd have to add a different distro listing from what I tried. Honestly, I did a quick attempt, it wasn't working. Made sure my commands was right and they were so I dumpted it. I can't remember a disto I changed out of faster in recent years.
