Firebase FCM send the notification with PHP but without link

i'm trying to send push notifications with FCM in PHP curl but the notification goes, is received, but when i click... the link does not open anything or even open the chrome/edge... Am i missing something?

The code:

        //receive user token        $token_user = $row['token'];        $credential = new ServiceAccountCredentials("https://www.googleapis.com/auth/firebase.messaging",            json_decode(file_get_contents($DIR . "cron/file.json"), true)        );        $token = $credential->fetchAuthToken(HttpHandlerFactory::build());        $ch = curl_init("https://fcm.googleapis.com/v1/projects/myproject/messages:send");        curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json','Authorization: Bearer ' . $token['access_token']        ]);        $data = ["message" => ["token" => "$token_user","notification" => ["title" => "Breaking News...."                ],"webpush" => ["headers" => ["image" => 'https://foo.bar.pizza-monster.png'                    ],"fcm_options" => ["link" => "https://google.com"                    ]                ]            ]        ];        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);        $response = curl_exec($ch);        curl_close($ch);        echo $response;

I tried change the url to relative path, to https. Tried with the old payload form and the newest but, nothing works.
