I'm in a desperate mode trying to get the submission of the form in the returnUrl page/template with the Freeform Plugin.
I'm trying to achieve an overview / confirm your details functionality. So, the form is sent and then goes to the returnUrl. Is there any chance I can get (maybe a twig variable) the submission but not in the query param of course (security issues).
I saw something here (in the ApiController)
$returnUrl = \Craft::$app->view->renderString( $returnUrl, [ 'form' => $form, 'submission' => $submission, ] );
From the overview page I need 2 actions: confirm (which will call another action - sync to some API) and one edit that will go back to the form.
