Insight AppSec workflow in ICON

Trying to build out a workflow that triggers via a webhook when AppSec completes a scan that generates the report for the scan and sends it out to the appropriate person(s). The issue I am running into is when the HTTP plugin generates the output it comes out as a string. I cannot figure out how to get the string converted over to a usable format to include in an email. I tried base64 encoding it to send it as an attachment but that doesn’t work. Any suggestions / has anyone done something like this before?
