redirect to a page after sent

hi, works great but i use:

<script>
document.addEventListener( 'wpcf7mailsent', function( event ) {
         if ( '2187' == event.detail.contactFormId ) {
    location = 'https://www.mydomain.com/thank-contacting-us/';
         }
}, false );
</script>

to redirect after sent.

after using your plugin redirect to a page after sent not working anymore, what i need to change?
i have try to on/off “Send CF7 mail as usually” but is the same.

thanks
