iOS and macOS native calendar application detects URL's from video conferencing apps (e.g. Webex, Zoom, Microsoft Teams, Google Meet etc.). Even though these apps are not installed on the iPhone, it detects from the URL that the URL is of video conferencing/voip app and shows a 'Join' button next to URL and video icon, also the application icon if application is already installed on phone and tapping "Join" will redirect to app and Joins meeting. For example if the URL is for Zoom meeting is pasted in the iOS or macOS native Calendar event, it shows are Zoom meeting with "Join" button and video icon to indicated it video conference. Does apple provide and api for this integration, I have app which also do a video conference with URL, what is the way to make my app's URL recognized as Video Conference and show "Join" button as other above mentioned application. Does anyone know how to achieve this or made it work for their application. Appreciate any help, thanks
