I have a service app which required files in config folder and assets folder so i have attached a volume with /app/data then,

I deployed filebrowser template but it already comes with a volume, so i'm confused how do I use filebrowser to create those folders and upload my files. which is attached to my service app

    volumes:
      - ./config:/app/config
      - ./assets:/app/assets

or is there a way to attach the same volume for both the services, or is there any other workaround please help
