DataSourceName Parameter is not working while configuring CDM util Function App

[Himanshu-Crowe]

I was able to setup CDM util Function App and blob storage event is also being triggered when a table is activated in D365.
In Application settings I am using SynapseExternalTable as DDL Type. SQLEndPoint setting is also working fine.

Problem arises at configuring DataSourceName. DataSourceName doesn't seems to be working. Synapse External Tables created are using default External Data source name which is using default database scoped credentials. My requirement is to use an existing Data Source which I am explicitly passing.
