lightning:empApi Embed the  lightning:empApi  component in your custom Lightning component to subscribe to a streaming event channel and receive event notifications. You can subscribe to any type of event channel on the Lightning Platform, including channels for platform events, PushTopic and generic events, and Change Data Capture (Developer Preview) events. The  lightning:empApi  component uses a shared CometD-based Streaming API connection, enabling you to run multiple streaming apps in the browser. lightning:map The  lightning:map  component securely displays a map of one or more locations using Google Maps. You can pass markers to the component to define the locations to map. A marker can be a coordinate pair of latitude and longitude, or a set of address elements: City, Country, PostalCode, State, and Street. Here’s the map component with one address.

An explicit  inherited sharing  declaration makes the intent clear, avoiding ambiguity arising from an omitted declaration or false positives from security analysis tooling. There is a distinct difference between an Apex class that is marked wi
