how to transfer settings from old fenix to new fenix

I purchased a new fenix 6 and I want to transfer all the sport settings (screens particularly) and ideally transfer all that I can on the new watch. pretty much like I do on my apple products every time I buy a new one.

I tried what is explained here: 

Can I Back up My Information and Settings on My Garmin Device?

https://support.garmin.com/en-US/?faq=AXV7LuWgc73v21nq6nbDa6

it's a good article but I cannot manage to get the fenix visualized as an external drive.  I've tried different ways and eventually gave up on that path. So I downloaded and installed Garmin Express, it sees my device, but there's no way I can use if to back up settings in order to install it on a new watch. 

It all seems very complicated while what I'm trying to do is basically copy a few configuration files from one device to another. Any help, please?
