How to use Uniswap Universal Router

Smart Contracts
1

I want to use UniversalRouter to do swap, and the function supplied in UniswapRouter smart contract is here.

function execute(bytes calldata commands, bytes[] calldata inputs, uint256 deadline)
        external
        payable
        checkDeadline(deadline)
    {
        execute(commands, inputs);
    }

here is a transaction data example in Arbiscan

Function: execute(bytes commands,bytes[] inputs,uint256 deadline)
