If you wanted to configure a custom IdP added to your Qlik SaaS environment, it will need to add a license for this.
You may contact our customer support team or your account manager to help you further on this, please go to https://community.qlik.com/t5/Support/ct-p/qlikSupport and start a chat (one of our customer support engineer will assist you on this) and if that doesn't work, you can still email customersupport@qlik.com
