"No Active Device" on my find my (macbook) so my friends can't see my location on their iPhone

These are the screenshots of my find my (macbook).

As you can see, i already set up all of the settings like location services, bluetooth, wifi, notifications allowed, literally i tried everything but nothing worked. In my find my profile, there's showing "No Active Device". But my device are okay, i updated it, i started to restart it, i tried to turn on and turn off the location.

Also in my apple id, it clearly says find my mac is on.

Anyway here's my mac specs in case it helps to find out whats going on

PLEASE HELP :( THANKS IN ADVANCE

sorry if i wasn't really good at explaining my problems. i hope yall could get what i meant. xoxo
