Postgres DB Custom Schema

When connecting label studio to a postgres backend what environment variables should be defined to use a schema other than “public”? Label Studio is being run via Docker and can connect to the postgres instance and populates the “public” schema with the necessary tables. Below is the docker-compose.yml used.

services:
  label-studio:
    image: heartexlabs/label-studio:latest
    ports:
      - "8880:8080"
    volumes:
      - ./ls_data:/label-studio/data
    extra_hosts:
      - "host.docker.internal:host-gateway"
    environment:
      - JSON_LOG=True
      - DJANGO_DB=default
      - POSTGRE_NAME=postgres
      - POSTGRE_USER=postgres
      - POSTGRE_PASSWORD=postgres
      - POSTGRE_PORT=54322
      - POSTGRE_HOST=host.docker.internal
