Access to records in a custom module

Access to records in a custom module

We created a custom module named Packages which is our main product. We created a bunch of Package records from an Administrator ID.

Our intent is only Admins will be able to create and update Package records. All Standard users will see those records and able to use them via a dropdown in Deals module.

However, the Standard users are unable to see any of the created records. On the other hand, they have the right to create new records. How do we set the access we need?

Thank you in advance for any help.
