Passing a custom SAML Attribute to third party


Okta is pretty new to our organization and every integration we have done has been standard mappings from AD. Talking to our admin we haven’t had to pass anything as a SAML attribute to a third party that wasn’t in AD. We now have a requirement from another party to do that exact thing. My experience with Okta is next to none, so I’m not sure on where to start for searching or documentation. If someone could help point me in the right direction or if you need more information to help diagnose the issue I will give you what I can.
