Okta SSO with Epic's MyChart system

Hi, I’m building a patient portal app and I want the my app to have SSO with Epic’s Mychart system. I have found on Okta’s site that “For patients, Okta’s Single Sign-On (SSO) enables simple, secure access to Epic MyChart, a web-based portal that centralizes all their health information in one convenient location.” (Ref: https://www.okta.com/partners/epic-systems/).

However, I couldn’t find any instruction on Okta’s site regarding how to configure in order to enable SSO access to MyChart.

Did anyone find related instruction or have any related experience? Thanks.
