Web App URL Handlers
Through the web app manifest, developers can configure a PWA to register for URL handling. If a matching HTTPS link from an associated web origin is activated in another application or the OS, this feature allows Edge to prompt the user to continue navigation with that PWA. A new PWA window is opened to handle the incoming link navigation. The developer must configure the web origin to acknowledge the web app association by using a .well-known/web-app-origin-association file.
Available from Microsoft Edge 93 to 101
