Management API, SAML Connection

When Creating the Enterprise SAML connection using the management API, I dont really see an option to enable the “Sign Out URL” also I dont see an option of how can I enable the “Login Experience” of “Display Connection as a button”

Even if I specify the SignoutURL and the LogoURL from the management API and create a SAML connection, when I come back to the Browser console and see the connection, the options “Sign Out URL” and "“Display Connection as a button” are disabled…

Can you please help how to make create the SAML connection with the Management API with the options “Sign Out URL” and “Display Connection as a button” enabled
