Cannot see data in newly created Custom Visual builder application when accessing it via SAAS.

Summary:

I have created a custom application in visual builder with data object created in VB itself, everything is working when I tested it out in VB, but when I have embedded the live url to the SAAS application (Embedding Visual Builder Apps in Fusion Apps), I am not able to see data or saved data via it.

Application access via VB directly

Application access via SAAS

Can this be because the user does not have access or an account in PAAS? If so, how can I make this application accessible to any SAAS user.
