RealtimeDB as a catalog in Presto
In the creation of Presto type Entities, the user has the possibility to create Presto Entities from Entities already created in the Platform in the real time database.
To do this, when accessing the creation of a Presto type Entity, the user must select the "realtimedb" catalog, and the associated schema and the Entities owned by the user will be automatically loaded.
...
You will then return to the Entities list, where the newly created Entity will appear.
