Automatically start jitsi meeting

Hi I am using the below code to start my jitsi-meet. I am looking for a way to automatically start the jitsi-meet with name given in the code itself. How can I achieve this?

        $(document).ready(function () {
            var domain = "meet.jit.si";
            var options = {
                roomName: "TestingMeet",
                width: "100%",

                    ],
                }
            }
            var api = new JitsiMeetExternalAPI(domain, options);
            api.executeCommands({
                displayName: ['nickname'],
                toggleVideo: [],
                toggleAudio: []
            });
        });
    </script>
    <style>
        .title {
            text-align: center;
            font-family: "Segoe UI";
            font-size: 48px;
        }
    </style>
</head>

<body>
    <div id="meet"></div>
</body>

</html>

Generate a custom name and pass it here.

Can I start or get link of Jitsi Moderated Meetings (Moderator & Guest link) from meet.jit.si by JS?
