How can I set a ringtone for a group of contacts with a certain label?

I want to set the ringtone for each contact with a particular label on my Pixel 2 (Android 11). Labels are a thing that contacts can have in the default android contacts app (from Google). There seems to be a lot of answers out there about doing this, but only when the contacts app has something *specifically* named "groups". There is nothing called "groups" in the default Google contacts app, but I think that labels are basically the same thing as "groups".
