For organisations that use Okta as their authentication method and user management there are times when you need to use the UMUser smartobject to get identity details in your app.
Currently you can not get first name and surname as separate elements and instead the name field returns the username which you then need to use logic to unpick which is prone to future dev changes.
Please expose the first name and surname fields in the smartobject because they are passed into K2 user database from Okta SCIM integration as seperate elements.
