connecting to local SPARQL endpoint

[lisestork]

Could you, if possible, provide documentation for connecting Schimatos with a local triplestore? I would be interested in loading and updating type and SHACL shape stores from the same endpoint via their corresponding named graphs. I have tried adding a new triplestore, filling only the field 'sparql endpoint' with http://localhost:7200/repositories/<repo_name> pointing to the GraphDB sparql endpoint, but no individuals from my repo can be retrieved.
