ThunderFarter But i'm not so technical is there any way to use telegram or such instead of messaging?
For this to work you will need to grand Notification Access permission to FindMyDevice which would allow it to read all notifications and look for that "fmd" text to activate commands. Once this permission is granted, you should be able to use any app to trigger commands. To grant, open FMD, then go to settings (gear icon top right corner) then tap Permissions, next, next until you reach the screen about handling messages from other apps - and grant the permission.
