Configure telegram with docker

I have a docker-compose.yaml file which runs traccar for me. The docs say tp add telegram notifications that I should edit /opt/traccar/conf but that doesn't apply for docker unless I exec into the container. I suspect I need to add a pameter into the the compose file but im not sure what to specify for the telegram config parameters.

According to the documentation on GitHub, you must mount the "conf" directory with the host.

--volume /opt/traccar/traccar.xml:/opt/traccar/conf/traccar.xml:ro \

See my setup:

 environment:
      - TZ=America/Sao_Paulo
    ports:
      - 33318:33318
      - 8082:8082
      - 5011:5011
      - 5055:5055
      - 5013:5013
      - 5027:5027
    volumes:
      - /home/user/satvix/logs/:/opt/traccar/logs:rw
      - /home/user/satvix/conf/traccar.xml:/opt/traccar/conf/traccar.xml:ro
      - /home/user/satvix/templates/:/opt/traccar/templates
      - /home/user/satvix/media/:/opt/traccar/media
      - /home/user/satvix/web/:/opt/traccar/web

You can also use environment variables to configure docker.
