How to purge old tasks in IFS Cloud

My customer gets all it new requests from SAP integration in 23R1.  The requests is created the same as would be done manually with these steps:

1. New Request - identify customer, location, problem, Service Catalog, and severity.
2. Request Details - select View and Release which creates the tasks that will be assigned manually or by PSO.
3. MWO - technician accepts, travels to, starts work, and completes the task.
4. Integration sends the completed tasks, documents, and survey responses to SAP.

The tasks in IFS Cloud are only useful for a short period of time, lets say 30 days, and they accumulate quickly, affecting query performance.    They want to know how to purge those tasks and if we have a way to do this.  I could not find a ready made projection or product that addresses this issue.  Can you provide me with some help on this topic?
