How to import Okta users from customer instance

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 a public app so we can get the client ID and secret to provide the OAuth for the integration and then get the access token to read Okta user’s data.

If we need to create an OIDC app on Okta, where can we create an OIDC app that’s public-facing?

Actually, we need OAuth integration with Okta. Our goal is to create OAuth integration on our platform so Okta admin can one click to grant Okta permission to us.

Then we can get the Access token from Okta to use their Read Users API.
