OKTA WS-FED Integration with Application

I have a system that will only accept WS-FED
i. First Name: http://schemas.xmlsoap.org/claims/FirstName
ii. Last Name: http://schemas.xmlsoap.org/claims/LastName
iii. Role: http://schemas.microsoft.com/ws/2008/06/identity/claims/role
iv. UPN: http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn

The accepts UPN as the way it fully authenticates (whatever value upn is). I am having an issue where I am just not seeing the UPN claim in the browser once I attempt to login using OKTA.

Can someone point me how I should be configuring this to be in there properly?

Thank you
