If your Navo account is connected to Microsoft 365, you can use Azure group GUIDs to create groups to trim your menu. Any users who are a member of the group can see the menu items, and anyone who isn't can't. You can find your group GUIDs by opening your group in Azure AD.

Azure Navigation

From your Azure portal, navigate to Azure Active Directory → Groups and select your group. On the right side of this page, you should see a string of characters with the label “Object ID”. This is your Azure Group Object ID (GUID).
