Add Shortcode to Calendar? Specifically in help field.

I've been building a custom SMS integration for my FluentBooking setup. I want to include a shortcode in the help field of one of the questions I added for 10DLC-compliant disclosure opt-in to text messaging. (Shortcode ensures consistency and logging for audit purposes.) It doesn't seem to work. Is there an alternative way to do this? Or can it be added in future feature releases?
