How to remove the Reassign option for the approvers in BPM Worklist in Invoice approvals.

We would like to disable or remove the reassign option for approvers in the BPM worklist notification for the Invoice approval process. Currently, the availability of this option allows approvers to reassign invoices to individuals who are not part of the defined Invoice approval workflow rules, which can lead to deviations from the established approval process.

I have tested several scenarios by disabling the Reassign option in the BPM Worklist Approval Workflow Access and Configuration. However, the approver is still able to reassign the task to active employees.

Attached document has the reference screen captures. Please review and let us know to remove RE-ASSIGN option.
