Lock my phone when the watch is disconnected

[safurniss]

Hi I previously had a Galaxy A90 5G and could configure SmarLock so that if my Galaxy Watch 4 became disconnected from my phone it would automatically lock.

I've now moved to the Galaxy S24 and will soon be getting the Watch Ultra.

How can I configure the same functionality with my S24 and Watch 4 as well as the watch Ultra ?

I want to ensure that if someone was to snatch the phone from my hand, that it would lock.

Maybe you can use auto lock, under secure lock settings, to lock the phone immediately when the screen turn off on your phone and then setup a routine to turn the screen off if watch disconnects. But, remember bluetooth has at least few meters range even more in open
