I'm using the Azure DevOps Agent Pool "Azure Pipelines". When I went to "Project setting" > "Agent pools" > "Azure Pipelines" and select in the top right corner the "three dots" - there I can select "Approvals and checks" on Pool level.
I've added there an approval, so that approvers should grant all deployments which are triggered for the agent pool "Azure Pipelines".
Now, when I will run a Pipelines using that Pool it's immediately failing and I couldn't find the place where I could give the approval:
##[error]The job is using protected resource(s) for which checks have not been evaluated queue:Azure Pipelines. For more details, refer to https://aka.ms/pipelinechecks.
Behind the link https://aka.ms/pipelinechecks I couldn't find anything regarding Agent pool approvals
