First time Flatpak user here, trying to use the Slack on Fedora 35 (now
that they're retired the RPM).

I am able to run the app, and the Slack window appears.

When I click on the "Sign In to Slack" button, however, it never brings
up a browser window in which I can log in.

> Failed to call portal: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name is not activatable

As I mentioned, this is my first time attempting to use Flatpak, so I
could really use some advice on how to troubleshoot this issue.

Thanks!
