Builder can't access GPG SSH agent
I use GPG as my SSH agent so I can use a hardware token to protect my secret keys. I'm not sure if this is a Flatpak/portal or Builder issue, but Builder on my desktop is unable to access my GPG agent, and it fails ungracefully (no permissions request or sandbox-aware message about the limitation).
I do not encounter this issue with a non-Flatpak installation of Builder.
