Python celery flower no monitor tab (no real-time grohics)

Question

How I can see a real-time tasks execution?

I'm novice in celery. I'm running celery but don't see a monitor tab

http://127.0.0.1:5555/monitor returns "page not found"

Here is how I'm starting it

Celery in the script

if __name__ == '__main__':
    REDIS_TASKS_BROKER = 'redis://localhost:6379/0'
    REDIS_TASKS_BACKEND = 'redis://localhost:6379/1
    app = Celery(main=__name__, broker=REDIS_TASKS_BROKER, backend=REDIS_TASKS_BACKEND)
    worker = app.Worker()
    worker.start()

Flower in the terminal (after running a script):

celery -A tasks --broker=redis://localhost:6379/0 flower --port=5555

See https://github.com/mher/flower/issues/1107. The monitor tab was deprecated with version v1 and replaced with Prometheus stats. You can either downgrade to v0.9.7 (but beware that it's not compatible with Celery v5) or follow this guide to setup the Prometheus integration.
