If this is a Digital Bot Flow, not a Bot Flow for voice, then you won't have access to the callback action, so will need to use the APIs through Data Actions to create the callback.
So, assuming you are using a Data Action to create the callback in your digital bot flow, (post /api/v2/conversations/callbacks)
As part of that API call to create the callback you can set data you want to pass along

From there in your Agent Script you can use Inputs (maybe) or another Data Action to access those values to display them to your agents.
