Galaxy Watch 5 vs Routines+

Hi Everybody!

I have been looking for solution for some time now, but was not able to figure out how to solve my problem. Can anyone help me with it?

Facts:

Watch 5 has “wearing sensor” that locks it automatically once off the wrist.

I keep my phone on full mute and only a selection of apps is allowed to send notifications to my watch, the less important ones I tend to check manually whenever I have time.

Expectation:

I would like to create a simple routine, that would switch my phone volume to on whenever my watch is off my hand.

Problem:

I cannot make this happen. The only Watch-related trigger available in Routines for me is Cinema Mode (no use in this scenario) and Bluetooth disconnection/connection (also no use when the watch is charging in other room or is just put on a table). There are also no triggers related to watch status like watch charging or watch low battery. Am I missing something here or is it just plainly impossible to get this done?

I would appreciate all help I can get here. My phone model is A35 5G and my watch is Watch 5 LTE.
