My endeavours in trying to toggle my AC on Wear OS

I have a Gree AC unit which I control with the Gree Climate integration. I have been trying to get a useable tile which shows me the current- and target temperatures, lets me change them, as well as toggle it on or off. It seems to be impossible to check these boxes all at once, so here I am asking for assistance.

What I’ve tried so far:

Thermostat widget

This has a nice UI for viewing all the data I'm interested in and I can even increase and decrease the temperature, but I can't toggle the actual state on and off. Also, the state shows as null, which might be a bug.

Template widget

While I have created a template which shows me all the data I need to see, it only displays states and provides no interactivity.

Either of the previous two, in combination with the Shortcuts widget

I thought the Shortcuts widget would be an okay workaround so as to have a separate toggle switch, but for some reason, when trying to add the AC as a favourite, the toggle state switch doesn't even appear in the list, just other modes.

Does anyone have an idea for what I could do to add a toggle switch to my watch?
