Event Merge for Google Calendar™ (MV3)

Chrome extension that visually merges the same event on multiple Google Calendars into one event. Updated for Manifest V3.

[Fork from the original Event Merge for Google Calendar™: https://github.com/imightbeamy/gcal-multical-event-merge] When using Google Calendar™ you may have one event on multiple calendars. For instance on your work and personal calendar, on your work calendar and your team's shared calendar, or on many co-work's calendars. These can clutter up your calendar and make it hard to read. This extension merges all those separate events into one event, and gives it strips with all the individual calendars' colors.
