If I remember correctly, that notification doesn’t actually come from AutoLocation (or SharpTools)… it’s one of the actions that you created as part of the Tasker profile (assuming you are following the guide by @destructure00 - link to guide).
Taking a quick look at that guide, it looks like the notification is created when high accuracy mode is turned on and the notification is automatically removed when high accuracy mode is turned off (eg. the Notify Cancel action).
If you want a separate notification for when the high accuracy mode is turned off, you could always add another ‘Notify’ action with whatever text you want in the same step as the Notify Cancel.
