Navigating a course: alarm on waypoint proximity?

I've uploaded a GPX file including a track and multiple waypoints to the Garmin inReach Mini 2.
When starting the navigation (course) I get on screen a "map" showing the route. You can also see the added waypoints including their names.

But... It looks like I don't get a signal/alarm when I'm in close proximity to a waypoint.
Am I missing something or is this function simply not present on this Garmin device?

I've read you can set a proximity alarm on different Garmin devices, but I can't find anything on the Mini 2 to do so.
It sounds pretty ignorant if you can use the Mini 2 to navigate but it's lacking proper support for waypoints (f.e. to mark springs / water sources).

Any workarounds for this? (other than splitting up the entire hike into a million separate courses)

Thanks
