Navigating a route created by Garmin Explore with turn by turn.

I was expecting that the device (Fenix 6x Sapphire) would use the map and navigate me on road between waypoints, as opposed to just showing me a straight line.

For reference: https://support.garmin.com/en-GB/?faq=v0rJAHy2hq3prHjRlxdRw5

Similar to how the device navigates you to a selected waypoint.

What actually happens is that I create a route on Garmin Explore (iOS) and sync it to the device. 

Then, on the device I select "Navigate" and in "Courses" select the created route. 

The device shows the route with straight lines between points.

Is there a way to actually navigate a course on the roads?

Thanks.
