What's the best navigation component for embedded apps?

I’m struggling to find an answer about which navigation component to use for embedded navigation. We’re already using the App Nav for primary navigation however we need another component for 2nd/3rd level navigation (e.g. sidebar, tabs) so merchants can navigate through different sets of products, features and settings we have.

  • The Navigation component is not flexible and can be confusing with the native Shopify navigation on the side, so I’m guessing it’s only recommended for non-embedded apps.
  • The horizontal Tabs are not recommended for app navigation according to the guidelines.
  • Someone recommended using the Action List, however, it doesn’t say anywhere should be used for navigation (but I saw Shopify Collabs app using it)

Any help is appreciated. Many thanks!
