Hi, I have build a Chatbot which works on a Assistant GPT (OpenAI) and also integrated the API Key and the Assistant Key from OpenAI. It also recognizes the assistant and acts according to the instructions. I have stored a knowledgebase in the Assistant (Excel file). However, it cannot access it within the botpress Chatbot. How can I implement this accordingly?

I had the same issue. Open AI uses Vectorbases and the Assistan Version is V2 now. This has to be set in the Bot template files.
