keybase CLI via flatpak app?

[p-sims]

I was trying to run keybase pgp gen but it appears this flatpak doesn't make keybase CLI available.

I tried using flatpak enter but I couldn't seem to find the relevent executable...

flatpak enter io.keybase.Keybase /Downloads/keybase-flatpak/io.keybase.Keybase/builddir/files/keybase/Keybase
error: Failed to execute child process “/Downloads/keybase-flatpak/io.keybase.Keybase/builddir/files/keybase/Keybase” (No such file or directory)

Is there a work round? Is this something to easily add to flatpak builder?

I have no clue how to do this, sorry. I know next to nothing about flatpak, this is all just copy-pasted together until I got keybase to start. ;)
