Why Intercepting Slack Push Notifications with a Chrome Extension is Impossible
It's impossible to intercept Slack's push notifications with Chrome extensions. Research explains the underlying reasons.
Research into intercepting push notifications from web applications like Slack reveals that it is not feasible due to the architecture of service workers. Notifications are typically sent from a service worker, which isolates them from the page's JavaScript context, preventing Chrome extensions from accessing them. This limitation highlights a significant gap in the Chrome Extensions API.
