Need help in embedding VBS page in fusion with sso

Summary:

Hi Experts

I have currently embedded my VBCS page in Oracle Fusion using page integration, but when the user clicks the tile to launch my VBCS page it is asking user to provide IDCS credentials for PaaS. I have came across the concept that users can login to fusion using IDCS or SSO and then when users click on VBCS page it will authenticate automatically.

Can you please help me with high level steps involved to achieve this please, i have gone through Oracle docs but i did not understand, if someone can help me with the high level steps that i need to follow in order to enable the SSO between fusion and VBCS. Thank You
