External_api.js iFrame

Hello,

I am using external api for an automated guest.
But I get always two of them.
How can I get only one participant using iFrame api?

Thanks for replies in advance.
Greetings
Jürgen

//onload:
const domain = ‘www.de’;
const options = {
roomName: ‘Room’,
subject: ‘Room’,
configOverwrite: {disableKick: false},
interfaceConfigOverwrite: {
DEFAULT_REMOTE_DISPLAY_NAME: ‘Zuschauer’,
HIDE_KICK_BUTTON_FOR_GUESTS: false
},
userInfo: { displayName: ‘Zuschauer’ },
parentNode: document.querySelector(’#myif’)
};
const api = new JitsiMeetExternalAPI(domain, options);

api.addListener(“videoConferenceJoined”, function (new_one) {
options.parentNode.src=“https://www.de/Room
});

window.onunload = function doHangup() {
api.executeCommand(‘hangup’);
};
