We do have a method for adding "not officially supported" argument types, but functions as a whole is sill experimental and undergoing changes to be more user friendly...

Once I wrap up the Assistants api, I'll dive really deep into functions and test custom argument types, like lists and maps

Thanks for the tip 👍
