In many guides (especially my use case at least) from some time ago, I see that when setting up "Sign In With Apple", you must verify the domain by downloading a txt file and hosting it in this path https://example.com/.well-known/apple-developer-domain-association.txt.
The question is that I have just configured "Sign In With Apple" and not only I have not found anywhere the button to download this file (neither where theoretically it should be in the Services ID settings nor anywhere), but apparently everything works fine without having done it.
This has been a recent change, is it no longer necessary to verify domains in this way? We are going to take this into production so I want to make sure everything is OK.
