Summary
When the user starts and joins a meeting using '/zoom start' slash command with their Personal Meeting ID, and then uses the "/zoom start" slash command again to create a new meeting (also with their Personal Meeting ID), a new Slack post is generated in the channel. When the earlier joined meeting ends, the Slack post for the new meeting is updated with a "meeting ended" status.
