How can I have more than one navHostFragment in one activity?

I would like to have three navHostFragments in one activity, all taking the same space, but each hosting a different navigation graph. Then using a fragment manager and a bottom navigation bar I would like to show each when needed (and hide the others), and that way maintain the current position the user has in each graph.

I am currently facing an issue when trying to have 3 of them in one activity and I get this error:

Caused by: java.lang.IllegalArgumentException: Binary XML file line #38: Duplicate id 0x7f0a0086, tag container_fragment, or parent id 0xffffffff with another fragment for androidx.navigation.fragment.NavHostFragment

This is my xml:

I'd recommend to have a look on Google's Android Architecture Components samples, especially to Advanced Navigation Sample because it Shows how to handle multiple back stacks with Navigation and a BottomNavigationView
