Feature Description

Include the AdSense menu item in the updated help menu.

---

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• When the AdSense module is active, the help menu has the additional menu item Get help with AdSense, which matches the Figma design.
• Clicking on the menu item opens the URL https://support.google.com/adsense/ in a new tab.
• The change is gated behind the setupFlowRefresh feature flag.

Implementation Brief

This issue follows the same pattern as #11815. Once it has been implemented:

• Export the AdSense help icon from the Figma design and save it to assets/svg/icons/ folder
• In assets/js/components/help/HelpMenu.js:
  • Import the AdSense help icon
  • Add the AdSense help menu item to the setupFlowRefreshMenuItems array using the conditional spread operator pattern (similar to how it's done in the menuItems array)
    • The menu item should only be included when adSenseModuleActive is true
    • Use the following properties:
      • href: 'https://support.google.com/adsense/'
      • icon: The imported AdSense help icon with width and height set to 24
      • children: __( 'Get help with AdSense', 'google-site-kit' )
    • Note: Do not set gaEventLabel for now, as GA events for the updated menu have not yet been defined. This will be addressed when defining the list of events for this phase of the epic.
    • Insert this item at the appropriate position in the array to match the Figma design

Test Coverage

• Update failing snapshots/VRTs if any

QA Brief

• Set up Site Kit with setupFlowRefresh enabled
• Ensure that the Help dropdown menu does not have an AdSense item
• Activate the AdSense module
• Ensure that the Help dropdown menu has an AdSense item that matches the Figma design

Changelog entry

• Include the AdSense menu item in the updated help menu.

Hey @hussain-t, thanks for drafting this IB.

One small detail - we shouldn't set gaEventLabel for the menu item, as we haven't yet defined the GA events for the updated menu. It might be the case we use the same event as the existing AdSense menu item, but we may use a new event name or category. We'll figure this out when defining the list of events for this phase of the epic.
