Note: You can @mention multiple people simultaneously.
You can also mention @all or @online in chats with less than 30 members (Figure 3 and Figure 4):

When you send your message, the person you @mention will receive a red alert in their notifications. Likewise, if someone @mentions you, it appears in your notifications in red too (Figure 5):

If you are mentioned in a public room where you are not a member, you will receive the notification but you will not be able to see the message unless you join the room (Figure 7, Figure 8 and Figure 9):
