export const withFormValues = (initialValues, validationSchema) => story => (
  <Formik
    initialValues={initialValues}
    validationSchema={validationSchema}
    onSubmit={values => console.log(values)}

    {story()}
  </Formik>
);

You can use a storybook action for onSubmit

import { action } from "@storybook/addon-actions";

const formSubmit = action("form-submit");

...
    onSubmit={formSubmit}
