From VRChat Wiki
Group Instances are also great for managing events with a high amount of people. For that situation, the VRChat Group Queues option will setup a waiting queue to process joining requests when the instance max capacity is reached. When you join the queue for an instance, you will be placed in and will receive a invite request when a slot becomes available. Once the request is received on your side, you have one minute to join the instance before your slot is given to the next person.
