;; For illustrative purposes only. You should normally do this via `user.behaviors`.
(lt.object/add-behavior! (first (lt.object/by-tag :my-tag-name)) [::my-behavior-name])
(lt.object/raise (first (lt.object/by-tag :my-tag-name)) :my-trigger-name "foo")

;; Note that in the above, we find our objects `by-tag`, but we can use anything that returns (an) object(s). For example `intances-by-type`, or even `by-id`.
