AngeloH.07167 (Customer) asked a question.
A customer asked us to integrate with Okta so they can import Okta users into our app's employee list for their team. Please help to assist how to create an Okta app so we can get the client ID and secret to provide the OAuth on our platform for the integration and then exchange Okta's access token to read Okta users' data.

You would not need a CIAM tenant to develop OIN template but anyone wanting to use your template to "create a public app" as you first described would.
You would use the "Build New OIN Integration" button found on the "Your OIN Integrations" screen as shown in the first screenshot you recently provided. Anyone wanting to use your template once approved and published will use the "Browse App Catalog" button found on the "Applications" screen as shown in the second screenshot you recently provided. The "Create App Integration" button you pointed to in the second screenshot is used to create generic apps not OIN templates.
