问题
I have the custom policies working correctly with Apple Sign In but once I submitted to Apple for review they rejected my app because the button doesn't use the proper design/branding. Is there a way to customize the "Sign in with Apple" button with a logo and colors?
From apple: Your app uses Sign in with Apple as a login option but does not use Sign in with Apple button design, branding and/or user interface elements appropriately as described in the Sign in With Apple Human Interface Guidelines.

Actually, I was able to customize quite a lot including the button background image, which is the logo by using a custom page and css. I just followed this tutorial: https://docs.microsoft.com/en-us/azure/active-directory-b2c/custom-policy-ui-customization
Just make sure to use at least one of their templates like Ocean Blue or Slate Gray. This you won't have to create new styles and images from scratch. Just modify as you desire.
