CLI/scripting support

Description

I was a happy user of gdm-tools.
I used it to automate the process of setting the background image anytime gdm packages were updated by the system.
Now that the repo isn't maintained anymore (and that feature no longer works), I can continue to manually set my GDM background image with this tool, however I've lost the ability to automate :( I need to manually set my background image every time GDM is updated and goes back to ugly gray.

Is there any way you can expose some operations on the CLI?
so we could do for example:

flatpak run io.github.realmazharhussain.GdmSettings set-gdm-theme {Option} [theme] [image]

Any other workarounds you can think of?
Thanks in advance!
