Get jest testing help

I have a simple Node application that takes form data from a website and saves to a Google sheets document. Wrote this some time back and now I am trying to write tests for it.

I have the submit function which is called when the client visits the '/submit' post route. Its content are:

// submit.routes.js

function Submit(req, res, next) {
  const { data, token } = req.body;
  const url = `https://www.google.com/recaptcha/api/siteverify?secret=${secret_key}&response=${token}`;

  axios(url, {
    method: "post",
  })
    .then((response) => {
      return response.data;
    })
    .then((response) => {
      if (response.success !== true) {
        console.log("err");
        throw new Error("captcha failed");
      }
    })
    .then(() => {
      schema.isValid(data).then(() => {
        updateSheet(data)
          .then(() => {
            res.json("Form submitted successfully");
          })
          .catch((err) => {
            res.status(504).send("error with submission");
          });
      });
    })
    .catch((err) => {
      res.status(504).send("error with form input or captcha");
    });
}

So far my test looks like this: // submit.spec.js

// First part 
describe("Check captcha", () => {
  it("captcha verification was successful", async () => {
    const res = { success: true };
    axios.get.mockImplementationOnce(() => Promise.resolve(res));
  });
  it("captcha verification failed", async () => {
    let errMessage = "Network Error";
    axios.get.mockImplementationOnce(() =>
      Promise.reject(new Error(errMessage))
    );
  });
});

// Second Part
describe("submit and update form", () => {
  it("should update google sheet", async () => {
    const update = { updateSheet: jest.fn() };
    res = { message: "Form submitted successfully" };
    req = {
      body: {
        name: "James", //Full object according to yup schema
      },
    };
    update.updateSheet.mockReturnValue(res);

    const result = await Submit(req);
    expect(result).toEqual(res);
    expect(update.updateSheet).toHaveBeenCalledTimes(1);
  });
});

So I'm missing the link between the capthca verification and schema validation -> schema.isValid before making the updateSheet test.
