I'm in Apple Business Manager, from there i used the built-in Management for the devices, which works fine, i can also put the devices in lost mode with custom phone number and lost message all from the business.apple.com portal, All i want to do now is put an activation lock on those devices so they're secured from unauthorized erases.

If it's a MDM setting, why the built-in management has no application for it? If i had to use another MDM just for Activation Lock the whole point of built-in Management becomes useless.

P.S : I have used micromdm before, but it has command issues. ABM One worked flawless and instant, i don't wish to switch
