Hi, how do I use the “clear history and website data” option under Settings then Safari in my phone if it isn’t highlighted? I can’t click on it, thanks

Welcome to the Apple Support Communities.

If you cannot Clear the history and cookies from Safari on your iPhone, iPad, or iPod touch - Apple Support, could you post a screenshot of what you're seeing?

I'd also recommend you Restart your iPhone - Apple Support and make sure iOS is up-to-date: Update iOS on iPhone - Apple Support.

When there's no history or website data to clear, the setting turns gray. The setting might also be gray if you have web content restrictions set up under 👉 Content & Privacy Restrictions in Screen Time.
