BUG: Flatpak install fails

[claviola]

Describe the bug

flatpak gives me an error:

error: Failed to install com.floatpane.matcha: Can't pull from untrusted non-gpg verified remote

Even though the repo was added with option "no-gpg-verify".

I'm trying to find a way to get around this, but it's probably better to just sign it (IMHO).

To reproduce

Follow the flatpak install instructions (tried on Flatpak 1.18.1)

Expected behavior

Being able to install matcha through Flatpak
