Filtering assets by geolocation using pythonSDK [Community Contributedl]

How can I filter assets by their geolocation using the python SDK?

from cognite.client.data_classes import GeoLocationFilter, GeometryFilter

mygeofilter = GeoLocationFilter(
    relation="within", 
    shape=GeometryFilter(
        type="Polygon", 
        coordinates=[[[7, 61], [13, 61], [10, 55], [7, 61]]]
    )
)

client.assets.list(geo_location=mygeofilter)

This approach works for files, but for assets I get:

CogniteAPIError: Unexpected value 'within' | code: 400 | X-Request-ID: fd1c5a73-a3d3-9ec1-bd97-039b4b1e0051
