Link to specific SharePoint site (O365 is federated)

I have found the following article detailing how to create a double-encoded Smart Link, but can’t seem to find any information about how the application is set up. We are already federated with O365, so I don’t know what kind of app to choose (SWA, SAML, OID) or how to configure appropriately.

Or is this not intended for use with an Okta chiclet?

Article: How can I create an application that sends users to a deep link in Sharepoint?

Any guidance here would be appreciated.

Anyone familiar with links to SharePoint pages?
