How to set variables after async function call returns?

const fetch = async () => {
  await function_here { ... }
};

const {
    data: mintData,
    write: mint,
    isLoading: isMintLoading,
    isSuccess: isMintStarted,
  } = useContractWrite(contractConfig, 'mint', {
      args: [ARGS_FROM_ASYNC_FETCH_CALL_HERE],
});

I tried doing

const {
    data: mintData,
    write: mint,
    isLoading: isMintLoading,
    isSuccess: isMintStarted,
  } = fetch().then((result) => useContractWrite(contractConfig, 'mint', {
 args: [result],
}));

However, that didn't work due to "Hooks can only be called inside of the body of a function component." How am I supposed to populate ARGS_FROM_ASYNC_FETCH_CALL_HERE from the async function if I can't chain promises?
