Bug: Users Can Join Room with Duplicate Name Without Receiving Error Message

[CoderSwarup]

Describe your issue

Currently, there's a bug in chat app where users can join a room with duplicate names without receiving any error notification. This behavior is unintended and can lead to confusion within the chat room environment.

Steps to reproduce

1. Open the chat app.
2. Join a room with an existing username.
3. Notice that the user is allowed to join without any error message.

What was the expected result?

When a user attempts to join a room with a name that already exists in that room, they should receive an error message indicating that the username is already in use. This will prevent confusion and maintain clarity within the chat room.
