Unable to connect with Azure SQL Database through Azure Ai Search?

Unable to connect to Azure SQL Database through Azure AI Search, as shown in this picture when clicked on Databases nothing is shown here but when I use endpoint of server less SQL on Power Bi, and Microsoft SQL Server Management Studio, it shows the name of all databases, I have also provided the permissions like Storage Blob Data Reader, Owner, Distributor, SQL Server Contributor to Azure Ai Search on Subscription level, but still unable to connect. The below screen captures shows that Power Bi, and MS SQL Server Management Studio are showing the names of the databases.
