Custom Google and Apple Signup/in buttons

I want to modify the default sign up and sign in buttons of Google and Apple for an iOS project keeping the changes as per their guidelines.

By default, these are like this:

Default Buttons

And I want to use it like this(G's border-radius updated to 6px, shadow removed, border-color updated and Apple's font size changed to 14px just to match it with Google's) :

Customised buttons

Now the confusion is due to the guidelines' do's and don'ts in Apple's guidelines, at one place it says:

To coordinate with your app design, you can change:

  • Title font. You can also adjust the font's weight and size.

And just below that, it says:

Prefer the system font for the title — that is, Sign in with Apple, Sign up with Apple, or Continue with Apple. Regardless of the font you choose, the title and button height of your custom button should use the same proportions that the system uses. Using the system font for example, the title's font size should be 43% of the button's height — in other words, the button's height should be 233% of the title's font size, rounded to the nearest integer.

And in Google's Guidelines, it says you have to stick with white or blue colour which is okay but in the custom button design page of google, it says anyone can change anything without hampering the aspect ratio and basic requirements.

SO how can I attain this so that the product will not be getting a revision from iOS's App store?

TLDR: How much customisation is okay for Apple and Google Signup/in buttons so that the app's design doesn't go into the revision from the App Store's side?
