Question

I read the documentation for the PublishPipelineMetadata task here - 
https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/reference/publish-pipeline-metadata-v0?view=azure-pipelines

But it is not clear on the purpose of this task. The name suggests it has to do something with publishing the pipeline metadata to the evidence store. But I have below questions for more clarification - 

1. What pipeline metadata it can publish?
2. What is evidence store to which the data is published and how it can be accessed?
3. Can we include the azure pipeline parameters defined in yaml for publishing the data?
4. If I get more questions and need more support for this task where can I contact for help?
