Help with Gnome-Network-Displays

Hi. I tried using Gnome-Network-Displays Flatpak version. I have this issue:

One of the following codec plugins is required for audio support. Clicking will start the installation process. → (Nothing to click actually!)

One of the following codec plugins is required for video support. Clicking will start the installation process. → (Nothing to click actually!)

A required firewall zone is not available and could not be installed. Please try again and enter the password when prompted or contact a system administrator.

I am using Nvidia GeForce 940M (Driver is good. I am gaming in steam with no issues), VLC, GNOME 47.3. Firewalld, pipewire. Mutter(wayland) and linux kernel 6.12.10-arch1-1. This app used to work well when I was using Fedora. Please help.
