PHP JeroenDesloovere's VCard download/import issue

I've installed the library via cmd and used the code like below. However file is not being downloaded at safari with "Safari can't download this file" error (translation may be wrong). In Android systems a 3 KB .vcf file being downloaded but it's not importing any data.

require_once('../vendor/autoload.php');

use JeroenDesloovere\VCard\VCard;

if(isset($_GET['download'])){
        
        // Output the vCard data to the browser
        header('Content-Type: text/vcard');
        header('Content-Disposition: attachment; filename="contact.vcf"'); 
        header('Cache-Control: no-cache, must-revalidate');
        header('Pragma: no-cache');
        header('Expires: 0');
    
         // Create a new vCard instance
        $vcard = new VCard();
    
        // Set the vCard properties
        $vcard->addName('Doe', 'John', '', 'Mr.');
        $vcard->addFormattedName('John Doe');
        $vcard->addCompany('Acme Inc.');
        $vcard->addJobtitle('CEO');
        $vcard->addPhoneNumber('+1-555-555-1212', 'WORK');
        $vcard->addPhoneNumber('+1-555-555-1234', 'HOME');
        $vcard->addAddress('123 Main St', 'Suite 100', 'Anytown', '12345', 'USA', 'WORK');
        $vcard->addEmail('john.doe@acme.com');
    
        // Output the vCard data to the browser
        echo $vcard->getOutput();
        exit; 
        
}
