iOS Safari has a special "QR" menu if you long-tap a QR code.

And this is built in to Android OS: "Search your screen" or "Circle to Search."[1]

Wow it even lets you copy the URL! (This is a gripe I've always had with Lens - it can read QR codes but doesn't let you copy the URL, so if you got redirected there's no easy way to get the original link.)
