Hey @shu.keung.lau,
Thanks for using the dev forum!
You can get your application to open using a URL Scheme. To set this up you would follow the steps mentioned here: https://stackoverflow.com/questions/25883113/open-ios-app-from-browser
To have you app open from the Zoom application, you would need to share a link with your URL scheme from within the application.
Thanks!
Michael
