DataZone empty PUB database in Athena

When opening Athena from DataZone portal project I can see no tables in the database with the _pub_db suffix. I expected to see them. Steps I took:

1. create a data source in AWS DataZone console (from Glue catalog that was created in Lake Formation)
2. in DataZone portal, being in correct project "publish data" button -> "automated publish" -> select correct data source -> data asset publishing: draft -> create publishing job I can see all the tables in project -> publishing -> published data. Also, if I make any of the data assets active and subscribe to it, from the same project, then the table appears in Athena '_sub_db' database and I can query it.

Is this behavior expected?
