NGINX pointing different docker compose containers

I am new to docker and I ran into an architectural problem: I have two sets of container (CUSTOMER1, CUSTOMER2) running in my computer by the same docker-compose file which, both, contains two same applications (APP1, APP2).

My question is: Is there a way, using an nginx server in the same host, to access to the desired app in the desired container (ex: APP1 into CUSTOMER1 container by browser link (ex: CUSTOMER1.MYPC.IT/APP1) through my computer using Windows containers?

Here I attach a graphical representation for better explaination:

image showing an host called "my_computer" which is running two different container, both with two applications running (APP1, APP2) with an external nginx server

Here, is the nginx.conf file from the nginx container:

worker_processes  auto;
events {
    worker_connections  4096;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  99999;

     server {
            listen 80;
            server_name localhost 127.0.0.1;
            resolver 127.0.0.11;
            location /APP1 {
                proxy_pass          http://test_app1/......;
                proxy_set_header    X-Forwarded-For $remote_addr; 
                proxy_read_timeout 300;
                proxy_connect_timeout 300;
                proxy_send_timeout 300;
            }

            location /APP2 {
                include  /etc/nginx/mime.types;
                proxy_pass          http://test_app2/......;
                proxy_set_header    X-Forwarded-For $remote_addr;
            }
        }
    }

Here, is my Docker-compose file:

version: '3.9'
services:
    app1basecontainer:
        image: app1baseimg
        build: ./APP1BASEIMG
        volumes:
            - apps1hared:C:\DEFAULT\APPPortal
        expose:
            - 8080
    app2basecontainer:
        depends_on: 
            - "appbasecontainer"
        image: app2baseimg
        build: ./APP2BASEIMG
        volumes:
            - apps2hared:C:\DEFAULT\APPPortal
        expose:
            - 80


volumes:
    apps1hared:
    apps2shared:

Thanks so much

2 Options:

1- Bind container ports to outside, then proxy to them:

services:
    app1basecontainer:
        ...
        ports:
            - 8080:8080
    app2basecontainer:
        ...
        ports:
            - 80:80

Then, in your Nginx conf:

server{
    location /APP1 {
        proxy_pass          http://localhost:8080;
    }
    location /APP2 {
        proxy_pass          http://localhost:80;
    }
}

2- Nginx container to your docker-compose, then apps and nginx are in the same network, and nginx can see apps containers. Then your nginx conf changes to :

server{
    location /APP1 {
        proxy_pass          http://CONTAINER_NAME:8080;
    }
    location /APP2 {
        proxy_pass          http://CONTAINER_NAME:80;
    }
}
