Where do the NGINX Snippets go?

[Stephan-P]

On my Openmediavault 8 NAS I use Nginx Proxy Manager (NPM) and I am a bit confused about the location for NGINX Snippets.
All the docker apps are running from subdirectories within the share 'appdata' on a separate docker drive.
E.g. /appdata/voidauth/ or /appdata/nginx-pm/

• If the snippets are stored in /appdata/voidauth/config/nginx/snippets then how is NPM (or nginx) going to reach them?
• Or should I store them in /appdata/nginx-pm/config/nginx/snippets?
• Or do I need to update the Compose for NPM or VoidAuth with an additional volume bind?
• OR should I indeed store them in a new dir in root: /config/nginx/snippets?

I suspect that the NPM compose may require a volume bind thing like this
Nginx Proxy Manager Compose snippet:

services:
  nginx-pm:
    ...
    volumes:
      - ./config/nginx/snippets:/config/nginx/snippets
    ...

This will lead to /appdata/nginx-pm/config/nginx/snippets where I can put the .conf snippets files
But that's like tainting the NPM Compose with something that is related to VoidAuth.

Doesn't it rather make sense, and is it possible, to save the .conf files within the /appdata/voidauth directory structure AND have the VoidAuth compose add a volume bind to the NPM project?
VoidAuth Compose snippet:

services:
  ...
  nginx-pm:                                               # Additional service definition in voidauth compose, adding a volume bind to nginx-pm
    volumes:
      - ./config/nginx/snippets:/config/nginx/snippets    # this is in fact appdata/voidauth/config/nginx/snippets to which nginx-pm has access

I decided to put the snippet files into 'appdata'/voidauth/config/nginx/snippets and modify the Nginx Proxy Manager (NPM) Compose with an extra volume bind:

services:
  nginx-pm:
    ...
    volumes:
      ...
      # nginx config code snippets folder, added for i.e. VoidAuth
      - ./config/nginx/snippets:/config/nginx/snippets
    ...

I also modified the VoidAuth Proxy Host configuration in NPM to include the prescribed custom config:

location / {
  include /config/nginx/snippets/proxy.conf;
  proxy_pass $forward_scheme://$server:$port;
}

After which I am able to reach my VoidAuth login page.
