How do I clear notifications in the activity section?

Managers

To clear notifications you can acknowledge, approve, reject, query or cancel any outstanding requests. 

• If a request is Approved, Rejected, Queried or Cancelled you can click Acknowledge and this will remove the notification from your sidebar. 
• If the request is from a teammate, you can select Acknowledge, Approve, Reject, or Query to remove the notification from your sidebar. 

Teammates

You can remove notifications by clicking Acknowledged to remove the notification from your sidebar.
