Tracking ascent/elevation gained

I've been familiarizing myself with my InReach Explorer+ and I can't figure something out. When tracking it doesn't seem to display/record the ascent/elevation gained on the device or in the Earthmate app. This seems like a critical piece of information that is missing. I'd love to rely on this device for everything but it seems thatI'll have to track on a smartphone app or GPS watch to get the information I need. Am I missing something or this is a very basic feature missing?
