Error One or more domains are invalid. Configure sign in with apple

Hi I am trying to configure sign in with apple for my app I am creating and it is asking for my domain and return url. I am putting in my domain twice because that is all i have. it is an app so I am not quite sure what to put. Can anyone please help me?

I am a first time app "developer" using no-code software called Adalo. I do not know how to code really. I'm learning slowly but I am almost done with this app other than a few things, this being one of them.

Thank you for any help.
I have the same problem just now, but I have resolved it.
for the domain name, don't include "https://"
for the return URL, you need to include "https://".

for example:
domain name: "example.com"
return URLs: "https:(slash)(slash)example.com/auth/apple/callback"
