This is a small browser extension for the PWA Gmail app on supported devices. The unread count badge will show on the taskbar or dock icon of the PWA Gmail app.

To add a PWA account via Google Chrome, click on the settings button (on the upper-right), and click on the menu option "More tools." After that, you can create a new shortcut, by clicking on the "Create shortcut" button.

After that, you can pin the PWA Gmail account to your taskbar. If you are running multiple PWAs, the icon will show the unread count of each account on the same taskbar icon by cycling through each account depending on when you opened the PWA account on your device.

This extension is very useful for the people who want to show the unread messages count of the app on the taskbar or dock icon.
