Can you sell ETH on Uniswap?

Sure, here's a description in English, simulating the tone of a questioner, within the word count limit: "Hey there, I'm new to the world of decentralized exchanges and I'm wondering if I can sell my ETH on Uniswap. I've heard that Uniswap is a popular platform for trading various cryptocurrencies, but I'm not entirely sure if it supports ETH. Can someone clarify if it's possible to sell ETH on Uniswap, and if so, what's the process like? I'd appreciate any help or guidance you can provide!
