Question: looking for means to run a final job step (that will be run locally)

[vsoch]

I'm developing the kueue executor, and as a final step I either want to pull the final artifact from the registry, OR tell snakemake that we should not expect output locally (and then instruct the user to pull). I am not able to pull during the completion of the job step because as it is using asyncio I can't call portforward:

asyncio.run() cannot be called from a running event loop

And I can't figure out the other two ways, so I want to ask for help.
