What's the best navigation component for embedded apps?

[antoniolopes]

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!
