Enabling rich text fields in custom code for structured data

I’m working on our new jobs page and have run into a snag. We are populating our Webflow CMS with job postings scraped from our recruiting tool. The JobPosting schema requires a description be included with each job post and it supports HTML Learn About Job Posting Schema Markup | Google Search Central  |  Documentation  |  Google Developers

Right now I can add all the fields I need to the structured data using custom code, except the description itself which is a rich text field. Does anyone know a workaround for this, or could the Webflow team please allow the use of rich-text fields in custom code?

Has anyone got back to you? I am also interested in the solution, please let me know if you have managed to find it
