REST API example for Check Configurations Query - Check Task

The REST call for this is documented here - https://learn.microsoft.com/en-us/rest/api/azure/devops/approvalsandchecks/check-configurations/query?view=azure-devops-rest-7.2&tabs=HTTP

However, there are no examples on how to use the "Check Task" type.  This type is for Gates in the pipeline.  There are few if any places to find which pipelines use Gates.   I am able to use the 'Environment' type and using the Environment ID.   

Please provide an example of what verbiage to use for the Check Task type and in the scenario where there is an Azure DevOps extension used as a gate.
