How to connect to avatica through Dremio v19.3

Hi,
We need to use Dremio connect Apache Calcite Avatica. And i’m new for Dremio and ARP.
So, is there have some reference material can guide me to do this?
And i search out something from github, but it’s not work for me.

I‘d write the codes, ARP YAML and ui.json according to Dremio Hub SqLite example and then built a jar file and put it in <DREMIO_HOME>/jars

After restart Dremio, we can see the option in Dremio portal and we can create a data source which type is avatica.

But when i looking into it, there is nothing shown, i don’t know how to show tables.

Anyone can help?
