Jenee's got the answer - hats off to you. I would add that the Mavic geotags individual images, so you can get the info by looking at the file properties on your computer, or by importing the images using DJI Go, then using a geotag aware photo app on your phone/tablet.
If you didn't do a photograph, your drone also records a log with continuous GPS location so you can get the same information, with a little work, after the fact. If you enable video cache, you get the time from the cached video, then look at your flight log to get the location on the map - not sure you can get the exact lat/lon that way but you can get close enough to match up on google maps. (Just remember to record video!)
As for your exact question - if you wanted, you could put the Mavic in waypoint mode, and record individual waypoints on the map. These might be a little awkward to actually use as a GPS destination for hiking.
I'm not experienced with the Litchi app (a 3rd party phone/tablet app similar to DJI Go 4), but I believe it will record the waypoints and export them later as text files.
Hope you find something really cool to hike to, like a dino skeleton, or a lost gold mine with tons of loot!
