Sharepoint Online OKTA SSO Implementation

Good Afternoon,

I’m trying to configure Sharepoint Online with OKTA SSO, so that when a user logs into sharepoint and then decides to click on a link to my custom .net 4.6 app (configured with okta oidc). There is a seemless transition between apps, where the user does not need to reauthenticate again.

At first I did not think two different types of okta sso authentication methods would work (saml or swa vs oidc), but i found this excerpt that says its possible:

Is this possible? and if it is, can someone please steer me in the correct direction of how sharepoint online needs to be configured with okta sso, to allow the seemless transition to the .net app. I found this article that I am planning on following, to configure sharepoint online, however I’m not sure if this is the correct path.

Any help would be greatly appreciated. Thank you in advance.
