How to pass components between two independent Angular modules?

Question

Angular

Angular 7.
There are two independent modules.
Module 1 declares a component that includes several more child components from module 1. Module 2 declares a
component that includes several more child components from module 2.
PROBLEM. module component 2 in the modal window
.
And from module component 2, show module component 1 in the modal window.
It is impossible to import modules into each other in both directions (cyclic reference).
I tried to create an intermediate module and declare the necessary components in it, but then the error is that the child components are not visible.
I think that the components should somehow be called dynamically or passed to some intermediate module...
HOW TO IMPLEMENT THIS IN THE CODE???

Answer 1

I would put it in the third module, which holds the components shared between modules

Answer 2

Transfer components common to both modules into a separate service
