App Actions on Windows are now available for Progressive Web Apps (PWAs) with Edge version 137.
App Actions enable users to invoke high-value features of PWAs directly within their current context.
To enable App Actions in Microsoft Store PWAs, developers need to define an Action manifest, set up a custom protocol handler, and package the app with PWABuilder.
Developers can also test their actions using the App Actions Testing Playground and create a PWA launch handler for precise control over how the PWA is launched.
