The problem is that devtools for a service worker doesn't show storage.

The solution is to open a visible page of your extension like the popup or options, then open devtools for that page (right-click it, then inspect).

In case your extension doesn't have a page, you can open chrome-extension://ID/manifest.json where ID is the ID of your extension shown in chrome://extensions page.

If you detach the Dev Tools (icon next to x in the top right corner) in a separate window, and press Ctrl+Shift+I while Dev Tools window is focused, you will invoke the Dev Tools for the Dev Tools window.

As far as I am aware, it's not possible for a docked configuration.
