Set spacefm as default FM

[root2185]

Debian GNU/Linux 11 (bullseye) x86_64
spacefm-gtk3 version 1.0.6-5

I used xdg-mime default spacefm.desktop inode/directory but it didn't work, so I added it manually to ~/.config/mimeapps.list.

But when I use for example "Open Containng Folder" in firefox-esr it uses the second FM in the list.

I use spacefm to handle the desktop and there it is the default FM.
I selected in the desktop preferences "Open folder using MIME associated application".
