Damage Protection Insurance & Airbnb API

I have the damage protection set up on all my channels. Which right now, are only 2. Direct bookings and Airbnb. 
For my DB's I pass that $13 charge onto the guest total, However, I do not see that charge passed onto Airbnb guests when they book. How do I create the surcharge on Airbnb's end? so that the guests booking from ABNB also have to pay the $13?

Thanks,

Generally, we do not recommend setting up a special charge for damage protection, but rather, building it into your rates as a cost of doing business.

However, if you do choose to add a special fee, remember that Airbnb only recognizes surcharges with a description using certain specific names:
