Is Zelle a PSP?

I'm curious to know if Zelle can be considered a Payment Service Provider, or PSP, in the world of finance and cryptocurrency. I understand that Zelle is a popular digital payment platform, but does it meet the criteria typically associated with PSPs, such as facilitating payments between individuals and businesses, offering secure transaction processing, and complying with relevant financial regulations? I'd appreciate your insights on whether Zelle can indeed be classified as a PSP, and if not, what sets it apart from traditional PSPs in the industry.
