I'm trying to use Sign in With Apple as an option for firebase authentication. When I follow the steps to set it up, I get to the part where I have to verify the domain and email for communication. I got the email part setup, but I can't find a way to verify the domain. Here is the domain firebase gave me "project-name".firebaseapp.com. I downloaded the txt file, but from there I can't figure out how to verify it. I went to the link Apple gave but nothing was there. Where and how do I verify the domain?
