Mention Syntax Guide:

1. Mention by User ID:
   @[uid] → Displays as "@user"
   Example: @[2234791809511721207] Hello!

2. Mention Everyone:
   @all → Mentions all group members
   Example: @all Please check this!

Notes:
- Mentions only work in GROUP chats (not 1-on-1)
- You can combine multiple mentions in one message
