Thank you for your post!
I understand that you're trying to implement a social login through your App that's already in the Microsoft Store. To do this, you can definitely leverage the Azure AD App registration located under the "Applications from personal account" tab.
I also notice that you mentioned verifying your domain, but your app is still showing as "unverified". When it comes verifying a publisher for your Azure AD App, this process will need to be completed through the Microsoft Cloud Partner Program (MCPP) using a Microsoft Partner Network (MPN) account.

I hope this helps!
