We are working to intergrate OKTA as our IDP to move towards SSO and we are wanting to pull several fields (most importantly the phone number field) from the devices detail page when a user logs into any of the OKTA driven apps on the device, so we can then pass it into our 3rd party Workday app (also leveraging OKTA). Could we use the mapping attributes here to grab the Phone Number ( I didn't see it in the list) and pass it into OKTA? Or would we need to use an API to handle this?
