Thank you for the quick reply! 
Unfortunately, the MessageToast element doesn't have all the features we would like. Currently, my team has a table with a history log of events, which updates in real time. We'd like the table's contents to be moved to a NotificationBar, so that the user can view the log at anytime, but also receive notification when it has changed.
Maybe there is a sap.m element that provides something like this?
Thank you!
