Implement Location Tracking in Experience Builder - same as JS API:
"Applications can find, track, and display the geolocation for a device with the Locate and Track widgets. Both widgets use the HTML5 Geolocation API to find the device's location and provide updates. Once your geolocation is found, you can zoom to the location, display a graphic, and follow along as your location changes. The Locate widget finds and zooms to your current location after you click the button, whereas the Track widget animates the view to your location at an interval. The Track widget is useful for building applications that provide driving directions and follow routes."
