How to set behaviors in Okta SDK?

With Okta SKD can verify and set up different polices. One of those is the sign-on policy when to trigger multifactor. Again most of the values can be set up with Okta SDK, but struggling to find a way to set up the behavior list (MF when the user has a NEW IP).
The RiskPolicyRuleCondition.class has an option to add a Behavior List, but how can I find the IDs of the behaviors I want to add? Seems strange to allow to add it, but no way (that I can find) to get a list of behaviors.
Any idea what I’m missing?

Setting behaviors via API is currently not supported.
