How do I reset the AR session? I found a solution to this in one of the issues, where the solution was to restart the activity, but that will not work for me because I am using the arfragment in one of the fragments in navigation view, so I tried resetting the fragment but the variables don't reset, which I can take care of by resetting them manually(a solution I found on stackoverflow). I was wondering if there was a better solution to this where I can just reset the session, without restarting the activity or the fragment the ARFragment is in. By "resetting session" I mean, return the ArFragment to the way it was when the app starts, no planes, no anchors, no node, where it shows the handmotion.
