workflowA generates artifacts which are needed to be consumed by workflowB.
Both workflows are triggered manually with workflow_dispatch, and I prefer not to use workflow_call or workflow_run events (as I do not want that workflowB will be triggered immediately once workflowA finishes).

For artifacts download I’m using actions/download-artifact@v4.
In order to reference the artifacts generated by workflowA I need the run-id, see download-artifact docs.

I would like that workflowB to pick up the run-id automatically, rather than manually entered it if defined as inputs to workflowB.

Is there a way in GitHub Actions to support that?
For example, is there a way to share outputs and/or environment variables (env) across workflows?

Any creative solutions would be much appreciated !
