I'm using react query with typescript. What is the type of the arguments given to the function?

export const useIsTokenValid = () => {
const { data: token } = useQuery<string | null>(['token'], getToken, {
refetchOnMount: false,
});
return useQuery(['isTokenValid', token], validateToken, {
refetchOnMount: false,
enabled: typeof token !== 'undefined',
});
};

export const validateToken = async ({ queryKey }: WHAT_TYPE_SHOULD_I_PUT_HERE) => {

  console.log('validating token');

  const [_, token] = queryKey;

  if (token) {

    const res = await axios.get<boolean>(BACKEND_URL + '/', {

      headers: {

        Authorization: token,

      },

    });

    return res.data;

  } else {

    return false;

  }

};

What type should I put where there is "WHAT_TYPE_SHOULD_I_PUT_HERE"?

Edit:
As suggested, I gave the type

QueryFunction<

  boolean,

  [string, string | null | undefined]

>

to the function. I don't get errors anymore on the function, but I get errors on the useQuery where I call that function, even though the types are correct (I think).

Theese are the errors:

null | undefined]> import validateToken No overload matches this call.
