Can I change behavior of close button? When user click close button redirect to page in my application
Yes. If you are self hosting. Just edit config.js on your server:
vi /etc/jitsi/meet/<meet.domain.com>-config.js
Uncomment “enableClosePage” and change it to “enableClosePage: true,”
When the end meeting button is pressed, it will redirect to /static/close2.html. Edit close2.html to say what you want or redirect somewhere else.
