Saml2 IdP Initiated - Add Item in result propert

I am using Saml2IdPInitiatedMvc.IdP sample to test IdP Initiated SSO. Once I login request is redirected to SP (which is IdentityServer4). Our client is reqesting us to include “returnURL” & “scheme” property in result. Could you please tell me how I can add those two properties?

Saml2IdPInitiatedMvc.IdP isn’t one of our example projects. Are you using our SAML product?
