Topic on Extension talk:Wikibase Client

I have my own installation of wikidata. I want to connect it to my wiki. But in the configs I see only direct access to the database on the server of the main wiki - repoDatabase. How can I specify a different DB server?

$wgWBClientSettings['entitySources'] = [ 'local' => [ 'entityNamespaces' => [ 'item' => 0, 'property' => 120, 'lexeme' => 146, ], 'repoDatabase' => "wikidata", //'repoDatabase' => false, 'baseUri' => 'my-dat/entity/', 'rdfNodeNamespacePrefix' => 'wd', 'rdfPredicateNamespacePrefix' => , 'interwikiPrefix' => 'd', ], ];
