SAML and security provider

I need to look at a requirement for a project that requires an integration of SAML with a Wappler app, specifically with the security provider action step. The server-side model is PHP and I am aware of the existence of: https://github.com/onelogin/php-saml .
What would be the best approach to tackle this? I’m looking to do something like what we have on the tutorials with a Facebook Oauth2 authentication that passes on the credentials to the security provider.
