If you are an administrator you will have a few extra options available to you. You can access the admin panel by clicking on the small button with the padlock on the lower left of your screen.
In the upper panel, you will see a list of logged in users, with buttons that allow you to mute, kick or teleport that user to you. Double clicking the button with the user’s name will teleport you to them.
In the lower panel you have the option to teleport all users to your position, to toggle mute for all users, and to delete all stickers from the world. Other administrators are immune to mute and kick commands.
