Question for AAD B2C and Application Insights:
We received this message:
"On 31 March 2025, technical support for instrumentation key–based global ingestion in the Application Insights feature of Azure Monitor will end. "

How will the connection-string based ingestion be realized in a Custom Policy.
We followed this docs:

https://learn.microsoft.com/en-us/azure/active-directory-b2c/analytics-with-application-insights?pivots=b2c-custom-policy
and only Instrumentation Key seems possible. Any advice on this would be much appreciated:-)
