Labels docker compose

[Akenjeru]

I'm using Docker compose
I want the container name to be displayed in notifications
labels:

• "diun.enable=true"
• "diun.metadata.ctn_names"

Am I using labels correctly?

  diun:
    image: crazymax/diun:latest
    container_name: diun
    command: serve
    volumes:
      - "/diun/data:/data"
      - "/var/run/docker.sock:/var/run/docker.sock"
    environment:
      - "DIUN_WATCH_WORKERS=20"
      - "DIUN_WATCH_SCHEDULE=0 */6 * * *"
      - "DIUN_WATCH_JITTER=30s"
      - "DIUN_PROVIDERS_DOCKER=true"
      - "DIUN_NOTIF_GOTIFY_ENDPOINT=URLmygorif"
      - "DIUN_NOTIF_GOTIFY_TOKEN=myapi" # get your token from Gotify UI
      - "DIUN_NOTIF_GOTIFY_PRIORITY=1"
      - "DIUN_NOTIF_GOTIFY_TIMEOUT=10s"
      - "DIUN_ENTRY_METADATA_CTN_NAMES=diun"
    labels:
      - "diun.enable=true"
      - "diun.metadata=ctn_names"

I configure diun to send me notifications in gotify about new versions of docker image, but it sends like this

I want it to write the name of the container
