Does anyone know the name of the below component, and whether/how it can be used programmatically for custom implementations? It would be very useful to notify our internal users of new custom features that our development team is releasing.
I noticed Salesforce is using a notification method in LEX that shows a dockable pop-up panel that is anchored to the bottom of the screen and is minimize-able. In this case it was alerting me to try using a new (Summer '19) feature.
