Azure B2C getting values from API return object

Question

I can't seem to get the values from the OutputClaims from my return object after making a REST API call to show up in the JWT token. I've tried this when I return a single string it works fine, but this is returning an object that looks like this from my B2CResponseModel object.

Do I have to do some kind of of mapping in the custom policies to match my return object or is there a way for me to just pull a value like I am trying to do below? Thanks!
