Hello author, after several days of exploration, I finally learned how to use this source code, great code! and I change the code to support EIP-1559 ,It's worked ok

But I used this code swap,It's show "Uniswap V3: Router" ,Manual swap onhttps://app.uniswap.org/#/swap It's show "Uniswap V3: Router 2"

Does this project support this "Uniswap V3: Router 2"? Is it possible to switch to "Uniswap V3: Router 2"？I used on optimism .

"V3 does not support setting this route?" I don't know if I understand it correctly
