Where does pre/post-snapshot actions get logged

I have a script that I want to run before/after creating a snapshot. Therefore, I would like to use “before-folder” and “after-folder” actions. However, I like to see what’s happening in those scripts, and I would like their stdout to be forwarded to kopia’s stdout.

Currently, I haven’t been able to figure out how to do that, or even if it is logged somewhere.
