Send meeting start alerts via DM to owners

You lose prep time when calendar events begin without a short reminder, leaving owners and attendees scrambling. Get concise direct messages before meetings so owners can prepare, ten minutes before start.

Overview

Too often meetings start with people unprepared because owners didn't get a quick reminder. This sends a short, contextual direct message with the event summary and link ten minutes before start, so owners can prep and meetings begin on time.
