APM policy for Webtop with NTLM & SAML protected resources

New to APM, I am trying to build a webtop with protected resources that have different auth requirements.

For example, I was able to publish a NTLM protected resource with SSO profile that grabs portal username & password and uses them for NTLM authentication.

I need now to publish another protected resource behind F5. The application is currently SAML configured with internal adfs.

How on my policy add SAML authentication?
