Hosting Django via ShinyProxy - Refused to display in a frame/ X-Frame-Options

Hello!
I am trying to host a Django app along with our Shiny apps on ShinyProxy. Unfortunately, I get the following error:

Refused to display 'https://our_url.com' in a frame because it set 'X-Frame-Options' to 'deny'

The section in the application.yml looks like this:

  - id: djangotest
    display-name: DjangoTest
    container-network: shinyproxy-test-net
    description: Django Testing
    container-image: django-docker
    container-env:
      - DJANGO_SECRET_KEY: 'not_very_secure'
      - DEBUG: True
    container-cmd: ["python3", "/app/manage.py", "runserver", "0.0.0.0:3838"]
    port: 3838
    container-volumes:
      - '/local/dir/:/app/'

I am aware that I am still using the Django development server but I just wanted to test this out. I am also new to Django and want to fix secrets etc. once I have a working example.

Thanks for any hints!

I found the solution. We have to set the x-frame-options in the DJANGO-App, not in ShinyProxy. Otherwise Django refuses to be displayed in an i-frame.
I put this in my settings.py:

X_FRAME_OPTIONS = 'SAMEORIGIN'
