How to add Flatpack BlackBox?

[King-of-penguins]

Apologies for my question, but I don't quite understand how to add a Flatpak BlackBox terminal.

For example, I successfully added the Kitty terminal:

gsettings set com.github.stunkymonkey.nautilus-open-any-terminal terminal kitty
gsettings set com.github.stunkymonkey.nautilus-open-any-terminal keybindings '<Ctrl><Alt>t'
gsettings set com.github.stunkymonkey.nautilus-open-any-terminal new-tab true
sudo nautilus -q

It works.

But how to add flatpak run com.raggesilver.BlackBox?
Do I have to use something like this?

gsettings set com.github.stunkymonkey.nautilus-open-any-terminal terminal 'flatpak run com.raggesilver.BlackBox'

This doesn't work.

My OS: Debian 11
GNOME 3.38
BlackBox 0.12.0 (Flatpak)

Everything is working.
