Is Zelle a money transmitter?

Can you clarify for me whether Zelle can be considered a money transmitter? I'm interested in understanding the legal and regulatory framework surrounding its operations. Specifically, I'm wondering if Zelle facilitates the transfer of funds from one person to another, essentially acting as an intermediary between the sender and receiver. If so, does this make it a money transmitter under relevant laws and regulations? Additionally, I'd like to know if there are any specific requirements or restrictions that Zelle must adhere to in order to operate as a money transmitter.
