how do I disable private browsing?

I had to choose “Allowed Websites Only” in Screen Time-Content Restrictions-Web Content and then toggle back to “Limit Adult Websites” and it works again.

On a Mac, use the Safari File menu New Window instead of New Private Window.

On an iPhone, see: Turn Private Browsing on or off on your iPhone or iPod touch - Apple Support

On an iPad, see: Turn Private Browsing on or off on your iPad - Apple Support

See:

Turn Private Browsing on or off on your iPhone or iPod touch - Apple Support

Use Private Browsing in Safari on Mac - Apple Support

But how to disable it? Not just turn it off/on. Content restrictions are still on, but now private window is an option. Don’t want this.
