How to get values of form before submit in useStepForm?

const { 
  // ... other properties
  submit 
} = useStepsForm({
  submit: (values) => {
    console.log(values); // Here you can access the form values
    // Modify the values if needed
    const modifiedValues = {
      ...values,
      // Add or modify fields as necessary
    };
    // Call onFinish with the modified values
    onFinish(modifiedValues);
  },
});
