Successfully sending push notifications, but not coming to the browser, how to fix it?

Question

PHP

Good day, I want to add notifications to my corporate website.
I'm testing this code, everything seems to be fine, but notifications are not displayed in the browser, although everything has been sent.
Maybe there are some ideas?

$YOUR_API_KEY = '111111111111111111111111111'; // Server key
        $YOUR_TOKEN_ID = '11111111111111111111111111111';

        $header = array();
        $header[] = 'Content-type: application/json';
        $header[] = 'Authorization: key=' . $YOUR_API_KEY;

        $payload = [
            'to' => $YOUR_TOKEN_ID,
            'notification' => [
                "title" => "Background Message Title",
                "body" => "Background message body",
                "click_action" => "https://dummypage.com"
            ]
        ];

        $crl = curl_init();
        curl_setopt($crl, CURLOPT_HTTPHEADER, $header);
        curl_setopt($crl, CURLOPT_POST, true);
        curl_setopt($crl, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
        curl_setopt($crl, CURLOPT_POSTFIELDS, json_encode($payload));

        curl_setopt($crl, CURLOPT_RETURNTRANSFER, true);

        $rest = curl_exec($crl);
        if ($rest === false) {
            return curl_error($crl);
        }
        curl_close($crl);
