Correct way to setup dynamic remote apps

[DisaPadla]

Hi, I'd like to understand how to properly work with dynamic remote applications. In my case, there is a host application, a remote application that I want to define dynamically, and an application responsible for storing the entire project. The store app can be used both as a host and as a remote application.

Currently, when I try to run the entire project, I get the following error:
Error: listen EADDRINUSE: address already in use ::1:4202
What am I doing wrong?

And a couple of additional questions:

How does the host application know it needs to run all the others if we define them as dynamic remote applications (look at the main branch)?
What is the standard approach for working with dynamic remote apps?
