Adding new environment variables/frontend configuration values

[beltebelt]

I am trying to add a new configuration value for some frontend changes I am working on in my fork. (Reference: #714 )
It should be a simple change, but since I am not very well versed with Django, I was hoping to get some inputs.

1. To start with, I have modified get_frontend_configuration by adding an additional config
   

   meet/src/backend/core/api/__init__.py

   Line 36 in 36b2156

   def get_frontend_configuration(request):

"whiteboard": {
  "collab_url": settings.WHITEBOARD_CONFIGURATION["collab_url"],
  "storage_url": settings.WHITEBOARD_CONFIGURATION["storage_url"],
}

2. Next, I modified settings.py / Base(Configuration):
   

   meet/src/backend/meet/settings.py

   Line 48 in 36b2156

   class Base(Configuration):

WHITEBOARD_CONFIGURATION = {
  "collab_url": SecretFileValue(environ_name="EXCALIDRAW_COLLAB_URL", environ_prefix=None),
  "storage_url": SecretFileValue(environ_name="EXCALIDRAW_STORAGE_URL", environ_prefix=None),
}

3. Finally, I have added the corresponding variables (EXCALIDRAW_COLLAB_URL & EXCALIDRAW_STORAGE_URL) in the following files

• env.d/development/common.dist
• src/helm/env.d/dev/values.meet.yaml.gotmpl
• src/helm/env.d/dev-dinum/values.meet.yaml.gotmpl
• src/helm/env.d/dev-keycloak/values.meet.yaml.gotmpl

After these changes, I can see the whiteboard.collab_url and whiteboard.storage_url in the frontend API call, however their corresponding values seem to be null. Would love any inputs on any other backend changes, apart from the ones mentioned above, that I might be missing.

TIA
