Latest AWS CLI does not see S3 Express One Zone buckets

I installed the latest AWS CLI. The output of aws --version:

aws-cli/2.14.5 Python/3.11.6 Linux/5.10.16.3-microsoft-standard-WSL2 exe/x86_64.ubuntu.22 prompt/off

After configuring, aws s3 ls lists my regular S3 buckets, but does not list the newly created S3 Express One Zone bucket. Specifying --region us-east-1 explicitly does not help.

I added the following inline policy to the user:

{
	"Version": "2012-10-17",
	"Statement": [
		{
			"Effect": "Allow",
			"Action": [
				"s3express:*"
			],
			"Resource": "*"
		}
	]
}

What else could I be missing?

P.S. Not sure if related, but in the Console, the "Find objects by prefix" box is grayed out for my S3 Express One Zone buckets.
