Is your feature request related to a problem? Please describe.
As stated in the documentation, flatpaks aren't supported by the wit.ai installer.

Describe the solution you'd like
I'm really not technical so maybe it's just not possible at all, but since the install works on snaps, I thought maybe it could also work on flatpaks.

Maybe changing the installation path to within the container when detecting the flatpak version of firefox ?

Describe alternatives you've considered
Using regular packages, but overall flatpak is the most mainstream way to install an app nowadays, so I think it'd be nice to support it.
