It is very easy. Here is my compose:

services:
  watchtower:
    image: containrrr/watchtower
    container_name: watchtower
    restart: always
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/localtime:/etc/localtime:ro
    command: --interval 10800
    logging:
      driver: local
    environment:
          WATCHTOWER_NOTIFICATION_URL: gotify://
          WATCHTOWER_NOTIFICATIONS_HOSTNAME: Fancy name
          WATCHTOWER_MONITOR_ONLY: true
          WATCHTOWER_WARN_ON_HEAD_FAILURE: never

Every 3 hours it will check for updates, send a message via Gotify and pull the new images. It will not restart the containers with the new images.

I only let me notify about updates. I don’t want autoupdates, because some projects may have breaking changes (looking at you Immich 😁)

I get a message from watchtower over Gotify and then I can read the changelog
