How does SushiSwap make money?

How does the decentralized exchange SushiSwap generate revenue in the cryptocurrency ecosystem? I understand that it operates as an automated market maker, facilitating trades between users without the need for a traditional order book. However, I'm curious about the specific mechanisms by which SushiSwap earns income to sustain its operations and potentially reward its users. Does it rely on transaction fees, token emissions, or a combination of both? Furthermore, how does the distribution of these earnings work, and are there any plans to evolve the revenue model in the future?
