Unable to Connect to VM

Hi All,

I was trying to connect Azure DevOps with Azure VM (Centos) using an agent software.

But I faced a error like 

"Access denied. Krishnagayathri Gopinath needs Manage permissions for pool Default to perform the action. For more information, contact the Azure DevOps Server administrator."

But I have administrator permission for Agent Pool for that particular project.

Please suggest your thoughts over this

Thanks in advance!
