Hi, I have a question with regards to authorization. We have a Medplum project that contains CarePlan data. There are also FHIR resources such as Tasks and Observations that are related to those CarePlans. And we also have Patients of course. Organizations have access through ClientApplications. In our remote patient monitoring system authorization is managed based on CarePlans. Authorization for an Organization, a RelatedPerson and a Practitioner are CarePlan-based. We use Medplum to exchange data only for Organizations for now. We have tried to find a solution in Medplum based on AccessPolicies and its criteria and the based-on property of CarePlan, Observation and Task, but it does not feel right. Can someone help with the right approach?
