Another helpful hint -> The Places extension holds the authorization status for a user in the extension's shared state. This shared state can be added as a Data Element in launch so that you can include the status in various workflows.
The first image below shows how you can define a Data Element for Auth Status. The second image shows that you can use any data element in Launch workflows as a condition or part of an action (i.e. post back).
How would this be valuable in a workflow? Let's say you want to optimize features in the app for users that have enabled location features. You can use the auth-status to create a segment for these users that can be used for messaging or to change the experience in the app.
