Public Facing Copilot trained on Sharepoint Document Library

Hello all,

Is it possible to have a public facing copilot that is able to read documents in a SharePoint library? I know we can require authentication, but the end users are not going to be logging in. The chatbot is to be embedded in our website for software/hardware troubleshooting. Is it going to be better to set up the knowledgebase a different way? 

Thank you,

-Jason
