How to delete a template?

Is there a way to delete a template sent to wear os watch as widget from the companion app and consequently from the smartwatch?

I suggest you change the title because your question does not match the topic well. (“How to delete a template?” – The delete key.)

Typically templates in Home Assistant are used in automations or sensors. They are not a stand-alone unit.

Ok, but i am talking about an option inside the companion app so i thought here could be the best place where i can get answers…
In other way, where you suggest me to put the question?

“How to delete a template” is about as vanilla as “how do I start my car”? If you want people to read your post, be more specific.

Again, “templates” is not a thing in Home Assistant like an integration or an add-on, so it is a puzzle what you are asking.
