Approval flow for responsibility access

Hello,

We would like to establish a process for an user’s responsibility access approval flow.

When a user requests for a responsibility, the admin will add the responsibility to the user’s account in User Management and this should kick off the approval management(AME) approval flow.  The approval notification should be sent to a group of approvers based upon the responsibility requests. Is there any document/link available for this process setups?  Thanks in advance.
