How can I pass a callback to Ray Tune but using TuneSearchCV?

Question

I am using Ray Tune's TuneSearchCV to perform a model hyperparameter search.

I would like to register a callback (in this case to simply print some extra metrics).

I have no problem writing the callback (see https://docs.ray.io/en/latest/tune/tutorials/tune-metrics.html for details), and to register it via

tuner = tune.Tuner(
    train,
    run_config=air.RunConfig(callbacks=[MyCallback()]))
tuner.fit()

But how can I register the callback with TuneSearchCV rather (or will the above do the job)?

Thanks!

Update: Crickets :( I'd also like to pass a Reporter (https://docs.ray.io/en/releases-1.11.0/tune/api_docs/reporters.html) via the Ray Tune sklearn API. Is that possible?
