MAST cloud dataset doesn't show level 3 data products

[bmorris3]

I'm trying to load a JWST level 3 observation from AWS. I run:

from astroquery.mast import Observations 

Observations.enable_cloud_dataset()

obs = Observations.query_criteria(obs_collection='JWST',
                                  filters='F090W',
                                  instrument_name='NIRCAM/IMAGE',
                                  proposal_id='2731',
                                  dataRights='PUBLIC')
products = Observations.get_product_list(obs)

The resulting products contain only levels 1 and 2

>>> set(products['calib_level'])
{1, 2}

The corresponding level 3 data products are available on AWS, and you can see them with the AWS CLI like so:

$ aws s3 --no-sign-request ls s3://stpubdata/jwst/public/jw02731/L3/t/o001/

...

Are level 3 products intentionally separated from levels 1 and 2? Is there a way to query for them?
