Include form fields as redirect URL parameters on an embedded form

For anyone searching for a solution where you can use the redirect settings from the form:

 window.addEventListener('message', event => {
 if (event.data.type === 'hsFormCallback' && event.data.eventName === 'onFormSubmitted') {
 const input = document.querySelector('select[name="input_name"]');
 const context = document.querySelector('input[name="hs_context"]');
 const contextObject = JSON.parse(context.value);
 const redirectUrl = contextObject.redirectUrl; // Retrieve the redirectUrl from the form settings

 if (input) {
 if (input.value && redirectUrl) {
 window.location.href = redirectUrl + `?input_name=${input.value}`;
 }
 }
 }
 });
