Angular with SAML


Hi Developers,

I was wondering how /where can I get the info for setting up Angular SPA with sign on method as SAML.
I switched on to the classic UI , but it lets you create a new application with sign on method as SAML only in case of Web platform .

Our front end is built in Angular, when I go Okta UI to create a new application in Okta and select the Platform as Single Page App (SPA) it shows the sign on method as OpenID Connect only. So is there a way to use SAML also in case of Angular/SPA or the OpenID connect is the only option.
