What table holds the script for a flow action?

[gjz]

I'm looking for the equivalent of the sys_variable_value table that is used by workflows for flow.

We have quite a few Run script actions in both our workflows and some of them have been converted to custom actions in our flows.

There are times I want to search on the script to find something that was done in the past, which I can do with workflow using the sys_variable_value table, but I've not found the equivalent for flows.

Does anyone know what table holds the script for a custom action in a flow?

in case you still looking for it , the table is sys_hub_step_instance , you can look at the varibles there for script
