How to download this Docker container as a Singularity container?

[Heng-Zhou]

The Docker container I want to download is here: https://quay.io/repository/cosmoscloud/ubuntu-gnome?tab=info

The Docker pull command is docker pull quay.io/cosmoscloud/ubuntu-gnome, so I guess the Singularity pull command may be singularity pull docker://quay.io/cosmoscloud/ubuntu-gnome. But I received an error when trying to run this command to download:

FATAL: While making image from oci registry: error fetching image to cache: failed to get checksum for docker://quay.io/cosmoscloud/ubuntu-gnome: reading manifest latest in quay.io/cosmoscloud/ubuntu-gnome: manifest unknown

What do I do to download this Docker container as a Singularity container? Thanks.
