如何形成对另一个域的 SSO 的 SAML 请求？

Question

I have an angular application where it needs to SSO with a third party application when clicked on one of tabs. The third party has provided a SAML endpoint that I need to hit with a payload, and that will generate cookies for me and then I get hit other endpoints like the /authenticate and /token. I was using postman to make a post request with the payload but it is does not look like it is working. Any opensource or any nuget package C# I can use to send SAML request. How do I form my SAML response?
