First time users will be prompted to authenticate using their TV credentials.
Hint: Make sure pop ups are allowed.
After authentication you will notice that TeamViewer has created an app token for your account.
Once authenticated a service case will be created placing the session link in the customer view when they open the incident.
You will notice that a group named "ServiceNow" has been created where your service cases will be stored.
To make sure your customized QuickSupport modules are being associated with the service case make sure to select this in the group's settings.
To review ServiceNow connection reports go into the TeamViewer Management Console --> Service Queue --> Connection Reports (report will import customer name from incident along with Incident # in description)
