@M, Panneer - Thanks for the question and using MS Q&A platform.
Azure DevOps is currently not supported in the Microsoft Q&A platform; the supported products are listed over here https://docs.microsoft.com/en-us/answers/products (more to be added later on).
In order to assist best on your query, I would request you to post your query in SO => Azure Devops dedicated support. Additionally, adding the [Azure] tag on SO will increase visibility as it is a Microsoft Sponsored tag.

Report any Azure Devops problems on Developer Community.
This will assist you with a faster reply to your query.
