Knowledge bases

Restore knowledge base

Restore a knowledge base and the documents and connectors archived with it. Active knowledge bases return unchanged without a new audit event. An archived workspace returns `409`; an archived containing folder moves the restored knowledge base to the workspace root. Workspace folder trees exceeding 10,000 folders return `413`. OAuth scope: `api:write`.
