Good Day Joyce,

Better late response than never I guess!

The information you require to add to servicenow needs to come from the IDP - Let's presume in this situation you're using Azure Microsoft - If you view within the Enterprise Applications within Azure portal there's "attribute" Fields to include within the SSO properties. This is to then be forwarded to the ServiceNow instance so you will then be able to include more information to be mapped.

Let me know if that's clear,

Best,

Jake
