I doubt that the dispensing module is generally usable by other implementations besides the one that originally wrote it (PIH/Mirebalais), but you're welcome to try.
You would need to manually make changes to the CIEL database, by adding a mapping for each concept listed here:
I think the right concept to use is https://openconceptlab.org/orgs/CIEL/sources/CIEL/concepts/163711.
The mappings would look something like this: https://openconceptlab.org/orgs/CIEL/sources/CIEL/mappings/583f35eb65baaa000771c0d0/
(I don't know if this is documented anywhere, and I don't have time to look any further, so you're going to have to look at the code to understand this...)
