Anyone got/know where to find iOS 14, 15, and 16 beta 1?

First time posting here. I’ve tried downloading the first beta for iOS 14-16 for the iPad 6 and iPhone 7, but since I don’t have a dev account I’m forbidden from downloading them. Anyone with a dev account or a previous download of them willing to upload them somewhere?

UPDATE: Found IPSWs for 15 for the iPhone 7 and 16 for the iPad 6
