Our team wants to create scheduled jobs to generate some reports to clients daily, weekly, and monthly, like as cron jobs mechanism. But I do not find related information in the Nakama documents and the Nakama forum.
Would you give me a suggestion on how to handle this part?
Sounds like something typical managed by an external system or scheduler that would look at analytics/event data to generate reports.
You can do this with Nakama by having a CRON scheduler make a server-to-server call to generate/send reports, or perhaps use the Go runtime to spin up a scheduler goroutine when the server starts and run the same function.
