Add service description in booking form

Hello Bookly Team,

Thanks for this awesome plugin. I’m currently using this plugin to build a booking system for oven cleaning. At the first step of booking form, I want to show the description (some info) of selected service in dropdown. How could I do that? How could I add an additional description field with every service entry in bookly backend? And how could I show service’s description below dropdown when a service is selected in dropdown in booking form?

Thanks!
