SSO Embedding the dashboard

I have created a looker dashboard and have to embed it to a web application using SSO or JWT authentication. I have tried to embed the dashboard in the localhost:8080 for a sample purpose, also I have added the domain in the embed domain whitelist. But the problem I am facing now is when I logged out from my looker the embedded dashboard is not visible it shows authentication issues 401. Also I am having these issues (in the attached screenshot)
