How to customize provision setting options for applications publish to OIN

I’m trying create a SCIM integration by SCIM 1.1 Test App and Add SCIM provisioning to app integrations (Add SCIM provisioning to app integrations | Okta). But i found some applications integration settings are different. See details in attached saleforce application screenshot. How to customize provision settings, like added button and specify the input ?

There are some OIN applications that were built by Okta and have certain specialised features/settings available. It is not possible to add certain functionality specific to these Okta-built applications, but you can specify in your OIN submission that certain variables need to be provided by the admin when configuring your integration in their Okta tenant, as discussed here: Publish an OIN integration | Okta Developer
