    • checkAvailableDownloads

      protected BaseMonitor.TransferControl checkAvailableDownloads(Instant referenceTimeStamp)
      Check the configured CADIP for new downlink sessions, whose publication date is after the reference time stamp:
      1. Retrieve all downlink sessions with publication time after reference time stamp (authenticating with either Basic Auth or Bearer Token)
      2. Convert JSON session entries into transfer objects
