You installed the Azure Pipelines app in Microsoft Teams and subscribed to an Azure DevOps project. You want Teams to only notify you about failed builds. What is the first command you should run from Microsoft Teams?

The correct first command is @azure pipelines subscriptions because it allows you to manage the notifications you receive from Azure Pipelines within Microsoft Teams. After running this command, you can then filter or modify existing subscriptions to only receive notifications for failed builds, or create a new subscription with that specific filter. The option @azure pipelines subscribe https://dev.azure.com/Contoso/Project1 is incorrect because it creates a new subscription for all build events by default, not specifically filtered for failed builds. While a necessary step to get notifications, it's not the first command to achieve the specific goal of only failed builds. Adding a Publish Build Artifacts task to the pipeline is incorrect as it's an Azure Pipelines configuration step related to storing build outputs, not managing Teams notifications. Enabling continuous integration for the project in Azure Pipelines is incorrect because it configures when a pipeline runs, not how notifications are delivered or filtered in Teams.
