Sorry to be rude-ish

Probably should be able to do the same with just:

    systemd-inhibit --what=idle --mode=block sh -c read

or the more easier ways

Or via api, which everything leads to

Noting other apps generally will inhibit via stuff sent through X/Wayland afaik, so this doesn't cover all methods
