Is Zelle a P2P service?

I'm curious to know if Zelle can be classified as a peer-to-peer (P2P) service. From my understanding, P2P services allow individuals to transact directly with each other without the need for a third-party intermediary. Does Zelle facilitate transactions between individuals in a similar manner, or does it operate through a different model? Clarifying this point would help me better understand the nature of Zelle's services and how it fits into the broader financial landscape.
