Getting Error while creating GCP VMs Shared Reservations

I have completed my organization setup and successfully configured production-level landing zones. However, when I attempt to create shared purchase commitments for two projects or set up shared reservations, I encounter the following errors:

Creating commitment "<commitment name>"

6 minutes ago - <project 1>

Based on your service usage history, you are not eligible for using the Shared Reservations feature at this time.

Please contact the GCP Sales Team (cloud.google.com/contact).

Creating future reservation "<reservation name>"

1 hour ago - <project 1>

Based on your service usage history, you are not eligible for using the Future Reservations feature at this time.

Please contact the GCP Sales Team (cloud.google.com/contact).

Note: I am able to create local reservations but it is not allowing me to create the shared reservations what I need to fix here
