Azure Application Insights Connection String

My App Insights connection string contains two URLs: IngestionEndpoint and LiveEndpoint and they are different. Given that I’m adding the connection string to the website, I need to adjust my CSP connect-src to be able to connect to these URLs. By looking at the network, it seems it’s only connecting to the IngestionEndpoint – will it ever need to connect to the other one? Or can I leave it off?
