Hiding the actions available on the notification popup

We will have to use a Pre-Processing Flow in the NotifyToAssigned notification found at System→Administration→Notifications→Default Notifications. Please follow the below process.

1. Under System→Administration→Notifications→NotificationFlows, select the AddProcessingFlow option,→enter a name for the Flow(for this case, Tekclan Test notification flow) and select Create. 
2. In the FlowDesigner, select the End step→change the mapping type of NotificationMessage input to BuildData→map Subject to NotificationMessage.Subject and Text to NotificationMessage.Text. Save and close the Flow. 
3. Under the Default Notifications folder, Edit the NotifyToAssigned notification→under NotificationFlows→check the Pre-Processing Notification checkbox→pick the created Flow→hit Save. 

The actions will no longer be available on the popup.
