Problem

When using the whiteboard feature with multiple users, the clear function only clears the content from the user who used the button and doesn't sync the action to the other user.

Steps to reproduce

1. Have two or more users join the whiteboard
2. Have one user add content to the whiteboard
3. Have another user try to clear the whiteboard
4. Observe that the whiteboard is only cleared for the user who pressed the clear button, and not for the other users

Expected behavior

The clear function should sync the action across all users and clear the whiteboard for all users.
