The Microsoft Graph helps us here too. By setting up these connectors, it becomes possible to seamlessly integrate Microsoft Copilot into different environments.
Copilot can then access an extended database, including third-party data, to provide more comprehensive and accurate support.

The following services are supported by the Microsoft Graph Connectors:

Azure Data Lake Storage Gen2
Azure DevOps Work Items
Azure DevOps Wiki
Azure SQL and Microsoft SQL Server
Confluence Cloud
Confluence On-premises
