Hi team
Our app is using Apple Login and its working fine. As our focus is moving towards the enterprise customers(B2B) rather than normal cosumer, so decided to remove the Apple Login(FB, Google etc), but for the some of our customers who are already logged with Apple Login, we wanted to keep this functionality in case they want to logout and login again.
So our question is this, Can we keep apple login functionality without showing the Apple login button ?
Flow will be -> User will be see a login page with option to enter name and email and a continue button. As soon as user will enter the name and email and press continue, our backend will inform us that the user is old user and logged in with Apple. After getting the information we'll open the Apple Login flow without any user interaction.
Please let us know in case of any confusion or doubt in explaining the question.
Thanks
