Describe the solution you'd like

1. Expand the FHIRPersistenceInterceptor interface to include beforeInvoke and afterInvoke methods

3. Expand the fhir-smart module with support for enforcing the SMART scopes defined in the "SMART Backend Services" part of the bulkdata export spec.

Describe alternatives you've considered
Put the auth code right into fhir-operation-bulkdata.
