Flatpak voip not working

Element (matrix) voip (audio and video) do not work with the Flatpak version on Fedora for me. The messaging works fine, but not the voip. It just hangs without connecting. There is no other option so I am using this Flatpak. I am guessing that I may need to grant certain privileges for the Flatpak to work, but am not sure which ones. Has someone else got Element working on Fedora that could help. Thanks.
