How to set up SSO in ComosReact based app

I have a requirement to configure SSO for CosmosReact based app. based on this

article Pegasystems Documentation

I have created the URL like this

https://pega-FD-test1-web.pegacloud.io/PRAuth/sso/app/alias/

But its not working and the system is giving an error of invalid URL and redirecting me to use the basic auth using userID and password.

Can anyone help?

@Manash_LSA This is resolved now. For Cosmos Based apps the URL pattern is

SSO URL Pattern

==============

http://host:port/prweb/PRAuth/app/AppAlias/authAlias

So my URL becomes

https://pega-FD-test-web.pegacloud.io/prweb/PRAuth/app/BrRf/sso
