@rahul1 I am currently working with Medplum's GraphQL API and need assistance with a specific query. I want to retrieve a list of all patients who do not have any `DeviceUseStatement `attached or who do not have a DeviceUseStatement for a particular device. Specifically, I'm trying to: 1. Get all patients who do not have a `DeviceUseStatement `for a particular device: Exclude patients that have a DeviceUseStatement for a specific device. Could you please let me know if this type of filtering is possible with the Medplum GraphQL API? If so, could you provide guidance on how to structure the queries to achieve this?
