Main Changes

We have added a new Slack reminder notification feature that automatically sends reminder messages to hosts via Slack direct messages before their scheduled events begin. This ensures that important appointments are never missed and provides ample time for preparation.

What's Changed

• Added automatic Slack reminder notifications 60 minutes before event start time
• Direct message delivery to event hosts
• Multilingual reminder messages supporting Japanese and English
• Detailed notification content including event name, guest name, and date/time
