InReach Mini reads out approximate distance from start of day. How can I get that readout on MapShare?

I can see when a track starts on MapShare.  My question is - I want to know the distance from the tracking start to the current location or on any of the track points.  I know that it won't be accurate due to the interval and straight line tracking.  But, the InReach mini device shows the user the approximated distance.  How can I get that reading while viewing MapShare tracks?  Thank you.
