Glue Table is recognized as unmanaged data asset

For demonstration purposes I have created two projects in Amazon DataZone. I added a CSV to an S3 bucket and crawled it into the pub Glue DB of that environment. Then I registered it into the catalog in DataZone. So far so good. Now I am trying to subscribe to it in the second project and query the data with Athena. But when I click "Subscribe" the following message appears: This is an unmanaged asset: DataZone will not be able to add this asset to any environments. You can reach out to the data owner(s) to find alternate ways to query this asset once approved. Even though in the picture it's clearly visible that the data asset is a Glue table. According to the documentation (https://docs.aws.amazon.com/datazone/latest/userguide/grant-access-to-unmanaged-asset.html) it should be possible to managed access to Glue tables automatically: For some of these assets, Amazon DataZone can can automatically manage access grants. These assets are called managed assets and include Lake Formation-managed AWS Glue Data Catalog tables and Amazon Redshift tables and views.
