Hi Joe

But how do you hide it until assessment is passed.

You can't do this out of the box. It would be easy enough to change in the code - just a case of changing state.isComplete to state.isPass on this line. If it's not shown on completion though, you'd need to consider how the user will know they are a) at the end of the assessment, b) have failed and c) how they'd reset for another go.
