By default, Progressier prompts users to allow notifications after PWA installation as this is empirically the absolute best time to do so.

However, you can ask users to allow notifications in the browser with the "Prompt for notifications in the browser" option available in the Danger Zone.

Still, it's not recommended for the following reasons:

1. On iOS, only installed PWAs have access to push notifications. So enabling that option will only affect Android/Desktop. The experience will be inconsistent across platforms.

2. If you also prompt users to install your app, they may have to allow notifications again after installation.

3. As an anti-spam measure, browsers sometimes automatically block notifications when requested before installation.

4. Allowing notifications in the browser after the PWA has been installed can sometimes cause notifications to stop working.

5. Users are more likely to allow notifications after installation.
