Execute command not working in ionic/angular when run on web

Execute command not working in ionic/angular when run on web

How are you running it?

I created the meeting using
this.api = new JitsiMeetExternalAPI(this.domain, this.options);
then add a button to mute/unmute using this command
this.api.executeCommand(‘toggleAudio’);
but execute a command not working when running it
My app ionic/angular when running it locally in the browser does not work but when I applied in the angular project working successfully so what my issue is with ionic/angular?

When you say it doesn’t work, do you see any logs or errors?
