Adding some info about public authwits from a relevant discord discussion

const action = asset.withWallet(wallets[1]).methods.transfer_public(accounts[0].address, accounts[1].address, amount, nonce);

await wallets[0].setPublicAuthWit({ caller: accounts[1].address, action }, true).send().wait();

asset - the token you are authorizing spending of
wallets[1] - the wallet that will be sending the transaction to the network
accounts[0].address - the address that the tokens are coming from
accounts[1].address - the address that you are sending the tokens to
caller - the address that will be making the call, this will be the uniswap contract address in your case i believe

from this test
