Need a way to know the last successful completed timestamp of a repeated job

[Extend-Apps]

Description

I'm using BULL to kick on integration jobs, and I need to maintain a lastSuccessSyncTimeStamp. I've tried everything.
The most obvious solution is to simply 'update' the job data in the 'completed' event

integrationQueue.on('completed', async (job, result) => {
await job.update({...job.data, lastSyncTimeStamp: Date.now()});
});

I've also tried it in the .process of the job

Minimal, Working Test code to reproduce the issue.

(An easy to reproduce test case will dramatically decrease the resolution time.)
