Adding Banter Trigger

[im_dw]

I am interested in triggering banter at more junctions than just at the start of the mission (ideally every X turns or when the alarm level increases). I found what seems to be a good list of trigger types in simdefs (like "TRG_ALARM_INCREASE") and what seems to be a call for Agent Banter in mission_util with "script:addHook( mission_util.doAgentBanter )". I'm just not sure how to put it together. Of course, this may be way more complicated than I'm thinking so feel free to tell me I'm asking for way too much.
