I believe this is because of code [here](https://github.com/sendbird/sendbird-uikit-ios/blob/9e7445970838a2648b90e32abb4160b3e5780157/Sources/SBUMain.swift#L431).

It won’t work for complex hierarchies like `UIViewController` inside `UINavigationController` inside `UITabBarController` inside `UINavigationController`.  
Is there any workaround for that, e.g. manually provide `UINavigationController` which should be used for navigation?

Our exact use case is:  
`UINavigationController -> UIViewController -> UITabBarController -> UINavigationController -> SBUChannelListViewController`

We are on version `2.1.13`.

Guys, any update on this? It causes really weird UX on our side since they see channel list, then create a new one then see channel list **again** in a modal which immediately pushes messaging page.
