HDL objects for element setup

Hi Team,

Currently we manually create the elements, input values and eligibility, which is a time consuming process, especially when adjusting these values. I read about the availability of HDLs for these objects in a cloud book. However, When I checked the view business objects, I am not able to identify them. Could you please clarify how we can access the templates for these business object elements, input values, and eligibility?

Thanks.
