Specifying constellation for HLS imagery

I’m bumping this thread with the hope of getting some additional guidance. I have not gotten my script to return only Landsat or Sentinel imagery from the HLS archive. The script always returns both. I didn’t find an example similar to what I am trying to do, so I modeled my code in the previous post after this example. In the HLS documentation, it appears I should be able to set the satellite constellation using input.data.dataFilter object, “constellation”, using the process API. The two options for “constellation” are “LANDSAT” and “SENTINEL”. My assumption is that I can set those variables using the “aux_request_args” argument in SentinelHubEvalscriptTask(). Is that assumption correct? If not, can someone suggest how I can specify Landsat or Sentinel when retrieving HLS imagery?
