cant redirect to download PDF

Hi
I’m taring to open a PDF in a new window after form is submitted, but it doesn’t work.
i’v seen a couple of tutorials and deterrent approaches.
but is all ways the same javascript code (and it doesn’t work at all).

1) put js the script in the child theme header directly
2) php function in the child theme function.php

the JS code:

<script type=”text/javascript”>
document.addEventListener( ‘wpcf7mailsent’, function( event ) {
if ( ‘1188’ == event.detail.contactFormId ) {
window.location.href = ‘https://e2youngengineers.org/wp-content/uploads/2019/07/Young-Engineers-Franchise-Report.pdf&#8217;;
}else{
echo ‘error: no redirection’;
}
}, false );
</script>

the form i’t self is on deme: on

please help me understand way it doesn’t work
