Hi @Rimple Shah
Thanks for reaching out to Microsoft Q&A.
That's correct, the application registration objects, the ones that contains the App Id, is only present on the tenant where the application was created / registered, which is known as "Home Tenant". Even though you can add and use the application on Tenant B, Tenant B would only have a Service Principal object as such object is created on every tenant that users the application. You can find more detailed information about these types of objects on the documentation below:
Thanks,
Fabio
