[NOTE] While we didn't have to toggle on ADB debugging for this to work, but if it doesn't work for you, maybe turning that option on will help. To do that, you need to first access the Development options by going to Settings > About and tapping the Build number 7 times. Then, go to Settings > Development options and enable USB debugging under the "Debugging" menu group.
