Unload dash app from flask

TLDR : What is the opposite of dash_app.init_app(flask_app) ? How to remove a dash app from a flask app ?

Hi,
I’m using a factory pattern to run dash apps :

  1. Create Flask App (server) in server.py

  2. Create oAuth registry (oauth) from Authlib in server.py

  3. Define my Dash apps without a server in python packages (folders with init.py)

  4. Load my Dash Apps into the Flask server in run.py, right before I run the server.

|---server.py 
|---run.py 
|---load_dash_apps.py
|---requirements.txt
|---git...
|---Dash_App1
    |---__init__.py (def the dash)
    |---layout.py 
       |-...
|---Dash_App2
    |---__init__.py (def the dash)
    |---layout.py 
       |-...
|---Home
    |---__init__.py (def the dash)
    |---layout.py 
       |-...

Every dash app is loaded through load_dash_apps.py.
Every dash app has the same navigator bar on top, and a content part.
The home app only has the navigator and is the first redirect after login.
The navigator allows to go from one dash to another.
What I want to do is to load only one app (starting with home), and when I click on the links in navbar, to redirect to a loader link with the requested app name as argument (url_for(“load_apps”,“the_requested_app”)). This url would remove the previously loaded app and load the requested app, in order to have one and only one dash app loaded at a time.

Basically, I want to undo dash_app.init_app(flask_app).
