After setting up an Application Insight connection string in the Admin Center, the full connection string remains visible to everyone meaning that anyone could, accidently or not, reuse this connection string on different tenants/environments.

This could lead to having data unduly ingested on that specific Application Insight app that could lead to data ingestion limits being hit earlier than expected (or unexpected high costs if no data ingestion limits are setup).

The Application Insight should be obfuscated so that only the starting characters would be shown, that would allow to identify the key being used, but wouldn't allow someone to copy and reuse the insight key on a different environment.
