Facebook Profile Pages (New Experience)?

I've changed 1 classic page months ago to a profile page. It was easy, found on a youtube video a link in description and I've just put the link on my normal page and it became a Profile Page. Now this method doesn't work! Does anyone know the technique to turn it to Profile Page? I've watched again some videos on yt and they said that you have to write to the facebook support, but it didn't work for me. I've tested these pages and they really have more reach than normal pages. A page from 30k-40k now is 130k, and I think just because of it. It's also easier to get verified with blue tick with them.
So anyone who knows anything please share with us!
