 This is a little tricky since you have to look at the source code of the plugin to figure out the `ID`. In the case of Spark, for example, the value of `ID` is used [here](https://github.com/flyteorg/flyteplugins/blob/v0.5.25/go/tasks/plugins/k8s/spark/spark.go#L424) here, defined as [spark](https://github.com/flyteorg/flyteplugins/blob/v0.5.25/go/tasks/plugins/k8s/spark/spark.go#L41).

 # When using the K8s secret manager plugin, which is enabled by default, the secrets need to be available in the same namespace as the task execution
 # (for example `flytesnacks-development`). K8s secrets can be mounted as either files or injected as environment variables into the task pod,
 # so if you need to make larger files available to the task, then this might be the better option.
