How to solve the problem with getting Google Access Token?

Question

OAuth

And am I making the request correctly? using axios in react

axios
      .post("https://www.googleapis.com/oauth2/v4/token", {
        grant_type: "authorization_code",
        code: CODE,
        client_id: CLIENT_ID,
        client_secret: CLIENT_SECRET,
        redirect_uri: URL_ADDRESS
      })
      .then(function(response) {
        console.log(response);
      })
      .catch(function(error) {
        console.log(error);
      });

So open the debugger and look at the server response, Google has a disgusting dock, but the responses of their services are usually adequate and make it easy to determine what the problem is.
