Redirect after submitting data to an external url

Hi,
I used in functions.php this code
add_filter(‘wpcf7_form_action_url’, ‘wpcf7_custom_form_action_url’); function wpcf7_custom_form_action_url() { return ‘my external url’; }

and I added in the additional settings of cf7 this code:
add_filter(‘wpcf7_form_action_url’, ‘wpcf7_custom_form_action_url’);

Now the form is correctly sending data to the external url but my problem is that after submission the form doesn’t show any messege and I don’t know to redirect to a thank you page. Do you have any idea how to do this?

Thank you

Luca
