Scan report of devops-VSTS doesn't send feeds into Defender for cloud - Devops Security section

I have created a project repository on VSTS version control. Also, I have created a DevOps pipeline where I installed and used an agent for Microsoft Defender for DevOps. After running the pipeline I found some scan report issues related to my coding which is expected.

Now I want to see this scan report into Microsoft Defender for the Cloud service of Azure portal.

So I have created an environment from Environment settings where I have authorized the Azure DevOps and Chosen the VSTS projects for which I need the scan feeds(Note: I can select the project under an organization but can't select the Repository(branches) which shows blank). See below..

So I have selected the Auto discovery of repositories option and added an environment.

Now, when browsing the DevOps security blade I can't see the VSTS repositories(TestDevopsPR) but I can see the Azure DevOps Git repository and its recommendations. Now question how to show the pipeline feeds into the Azure portal.
