Continuing discussion from- https://chat.fhir.org/#narrow/stream/179283-Da-Vinci/topic/Prior.20Authorization.20Q.26A/near/286092887

Currently DTR links come back as part of Cards that are displayed to the physician, however as we discussed often the physician will prefer to let staff handle it, or the contents may be entirely administrative information that doesn't require their input.

Instead of using Cards, we should prefer System Actions via updating http://hl7.org/fhir/us/davinci-crd/2022May/StructureDefinition-ext-coverage-information.html to have an extension defining the URL and the appContext as if we had received a https://cds-hooks.org/specification/current/#link in a card. We would expect it to to be populated whenever the extension has one of the http://hl7.org/fhir/us/davinci-crd/2022May/ValueSet-coverageGuidance.html values meaning that there is DTR questionnaire.

That way we can more clearly store and route the DTR link to whichever user can best  handle it (be it the physician choosing to, or staff following up).
