Using the umbraco-package.json, I have declaratively created the following extensions: section, sectionSidebarApp, menu, menuItem 3x, workspace 3x. All Menu items are connected to the Menu, and each one to a Workspace through an entityType. When I click the menu items I can successfully render content (in this case collections) in their respective workspace. Is there a way to declaratively add child-items to one of my menu items and render content for each one of them in workspaces? Could it be done programmatically with event handlers? e.g. see render function in the attachment Is a tree the only other option and how can I hook a tree into the existing menu? https://cdn.discordapp.com/attachments/1316773686220685372/1316773686358839326/image.png?ex=675c448f&is=675af30f&hm=cb6edbe5ee09941c1b457441e6d5d95e586db215ab6859c4c32ee10007c8d0cc&
