I'm sorry, but currently, it's not possible to install a PWA from Arc!

Although the beforeinstallprompt feature is present by default in Arc, there is no installation prompt UI. Therefore, if your app includes a custom install button, it won't have any effect.

If you're using Progressier for your PWA implementation, users attempting to install your PWA from Arc will instead be prompted to try from a different browser that supports installation. See below:

One of the benefits of using something like Progressier instead of building your PWA implementation manually is that it remains consistently up-to-date. So if Arc introduces support for PWA installation in the future, we will automatically adjust our logic accordingly!
