Connect Edge Touring to Ebike via ANT?

I got a new ebike (with Fazua Ride 60 system) and wanted to use my old Edge Touring with it.

The Edge Touring is updated to 4.20, but I don't find any way to connect it via ANT to the ebike.

The original manual from 2013 says it will connect, but no ebike option appears in the menu when holding the unit within 3 m of the ebike with the system turned on, as stated by manual.

Has this capability been removed, or does it need to be activated in some way other than just getting the bike and the Edge near each other?
