How to pull stats from a google cloud tasks queue that has finished? #5276

I'm trying to figure out how to pull the following stats from a Google Cloud tasks queue that has finished executing. I'm running a queue Mon, Wed, Fri every week, and I need to get some useful stats once the queue finishes every time.

• Nr of dispatched tasks
• Nr of successful tasks
• Nr of unsuccessful tasks (all retries failed)
• Timestamp queue execution start
• Timestamp queue finished
• Preferably also retrieving the payload of all failed requests if any

I can only find this doc: https://googleapis.dev/nodejs/tasks/3.0.2/google.cloud.tasks.v2beta2.QueueStats.html

But I can't pull the needed data from there.

Or do you need to pull this info from logs explorer or another service?

Preferably I want to configure this as a webhook meaning once a queue finishes, it triggers an endpoint that generates this data.
