Ideas on how to connect Copilot to KnowledgeOwl

My company uses KnowledgeOwl as our knowledge base and I am working on connecting Copilot to the knowledge base using Copilot studio. The knowledge base is hosted using their domain and behind our SSO authentication. I am struggling to figure this one out, because it seems like it is limited to only connect to public websites and sharepoint sites. I was wondering if anyone else here would have any ideas on how I can accomplish this, other than migrating to SharePoint.  Thank you!
