I want share my e-mail in one website where I logged in with Sign in with Apple. But there is no that option in my Apple ID profile.

That is the problem.

Here: https://support.apple.com/en-us/HT210426

At "View the apps using your Apple ID", "go to Apple ID settings on your device or sign in to your Apple ID account page."

I can not find the necessary settings.

On your iPhone, iPad, or iPod touch

1. Open the Settings app, then tap [your name].
2. Tap Password & Security
3. Tap Apps Using Your Apple ID.

Empty. No any app or website.

The same on Mac and on the web.

I'm about this function: https://support.apple.com/en-us/HT210318

When I first time login on one site, it asked me to provide my name and email address. I chose 'Hide'.

Now I want to change this.
