How to access postgresql database running on Docker volume from database client

I have an asp.net (version 8) webapi project that I have set up to work with docker.
I have the container that runs my API and a volume where I put my database.
It works and I’m able to run API endpoints to get my data from the postgresql database.
I want to be able to view the database running in the volume though.
How can I do this?

I’m using a Visual Studio Code plugin called PostgreSQL (Postgresql management tool by Chris Kolkman) and I can connect to the postgresql database I installed on my operating system but not the one that is running on my docker volume.

Here is my docker-compose.yml file

services:
 #asp.net web application
  webapp:
    container_name: shop-back-api
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "5999:5999"
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - Database__ConnectionStrings__DefaultConnection=Host=db;Port=5432;Database=shopback;Username=postgres;Password=XXXXX


  #postreSQL database
  db:
    container_name: shop-back-db
    image: postgres:latest
    ports:
      - "5432:5432"
    environment:
      POSTGRES_DB: shopback
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: XXXXX
    volumes:
      - postgres_data:/var/lib/postgresql/data

volumes:
  postgres_data:
      

I also have the "Docker" extension installed and I can view my images, containers, and volumes from Visual Studio Code but I’m not sure if this can help me as it doesn’t give me access to the database running on my volume.
