I found partial answer for my problem from here:
In the answer mentioned DELETE https://{ {catalog_end_point}}/api/atlas/v2/entity/uniqueAttribute/type/<entity_type>?attr%3AqualifiedName=<entity_qualified_name>
However, I am not sure how to find <entity_type> and <entity_qualified_name> for other Azure/Microsoft services for example Azure Synapse and Power BI that have been scanned in Purview.
Please help.
