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

Question

I'm trying to figure out how to pull the following stats from a Google Cloud tasks queue in the past that has finished executing filtered by date perhaps? I'm running a queue Mon, Wed, Fri every week, and I need to get some useful stats once the queue finish everytime...

• Nr of dispatched tasks
• Nr of successful dispatched tasks (200 status code)
• Nr of unsuccessful dispatched tasks (Meaning all retries failed for a task)
• Timestamp queue execution start
• Timestamp queue finished

Node.js solution or using google cloud cli is fine.

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

But it's not what I need really..

Alternatively, I guess a solution is to just trigger a webhook event when there are no more tasks in the queue. That could work as well, and I just log the individual requests to a db table, and then once the queue has finished I can pull the data I need from the db. So instructions how to configure the webhook event for when there are no more tasks in a given queue with google cloud platform is also an accepted answer.
