Thanks for posting your inquiry via Okta Community Portal.
If I find your inquiry correctly --you can leverage these two feature in Okta: (1) Access Request Workflow feature or (2) App Admin Role.
(1) The Access Request Workflow feature is a complete, multi-step approval workflow through which end users can request access to apps. Admins can designate approvers to grant users access for self-service applications. This is an Early Access feature. To enable it, you may need to contact Okta Support.
