If you want to tag someone in a message, you can easily do so by following these straightforward steps:

1. First, you need to find the person's name in the chat window or on the right side of your screen. This is where participants in the conversation are listed, making it convenient to identify who you want to tag.
2. Once you have located the name of the person you wish to tag, simply click on their name. This action will automatically insert their tag into your message, ensuring that they are mentioned directly.

By clicking on the user's name, you are not just tagging them; you are also ensuring that they receive a notification or a highlight that indicates the message is specifically directed towards them. This feature is particularly useful in group chats or discussions where multiple participants are involved, as it helps to draw the attention of the tagged individual to the relevant conversation point.
