In ActiveMQ peer-to-peer, will consumer B get the message if consumer A does not confirm?

seniors, rookies have been watching ActiveMQ recently. I would like to ask if the queue of ActiveMQ requires client confirmation mode, if message 1 is obtained by consumer A but is not confirmed, will ActiveMQ send message 1 to consumer B after a period of time?
