Hello,

I have a usecase where I need to report metrics from workflow to dd. I wanted to check if there is a way to inject dependencies in workflowImpl so that these metrics can be reported to dd ?

Injecting dependencies to workflows is not recommended and supported as it is very error prone due to determinism requirements.

For metrics we recommend using the included integration. See [Workflow.getMetricsScope](https://github.com/temporalio/sdk-java/blob/b9b41e0cabae0208b2d6c8efc0cdc5156b52fdbe/temporal-sdk/src/main/java/io/temporal/workflow/Workflow.java#L1220).
