Add an Unsubscribe from List button similar to ProtonMail

I apologise if this idea has been suggested before, but I'm sure many people also get spam emails or have been signed up to a mailing list without knowing it.

The idea is to have a front scan an email for an "unsubscribe from mailing list" link in the email and, if found, add a button at the top that just redirects to this. A similar function is available on other services such as Proton mail.

This saves having to search an email for it and makes managing emails a lot easier. It should be a relatively simple thing to add, and personally (and I'm sure others) would find it extremely useful.
