App Actions on Windows have expanded to include Progressive Web Apps (PWAs) starting from Edge version 137. Developers can now publish their PWAs to the Microsoft Store, allowing for enhanced user interactions. App Actions enable users to access key features of an app directly from their current context, reducing distractions from switching between applications. For example, the note-taking app Goodnotes allows users to send text directly to the app without toggling windows. Developers can integrate App Actions into their Microsoft Store PWAs by defining an Action manifest, setting up a custom protocol handler, configuring the app as a share target, and packaging the app for the Microsoft Store using PWABuilder. Optionally, developers can define a PWA launch handler and test actions using the App Actions Testing Playground.
