Why does iPhone not appear in Mac Safari Develop Menu?

iPhone 11 Pro
iOS 13.5.1
MacBook Air 2020
macOS Catalina 10.15.5
Mac Safari 13.1.1

Develop Menu is enabled in Mac Safari
Safari > Advanced > Web Inspector is enabled on the iPhone.
I have Safari open on the Mac, and a web page open in Safari on the iPhone.
I connect the iPhone to the MacBook with a USB/Lightning cable.
I get the "Trust this Computer?" dialog, click "Trust", and enter my passcode.
I open the Develop menu in Safari on the Mac.
My iPhone DOES NOT appear in the develop menu.

I tried resetting Location & Privacy in the iPhone Settings, but it doesn't make any difference.

I have same problem. Did you manage to solve it?
