 The chatbot will connect to the Mattermost server and start listening for messages.
-When a user mentions "@chatbot" in a message or sends a direct message to the chatbot, the chatbot will process the message, extract text content from links (if any), handle image content using the Vision API, and send the response back to the Mattermost channel.

-
-You can customize the behavior of the chatbot by modifying the following variables in the script:
-
-- `max_response_size`: The maximum size of the website content to extract (in bytes)
-- `max_tokens`: The maximum number of tokens to generate in the response
-- `temperature`: The temperature value for controlling the randomness of the generated responses

 ## Known Issues
 
 While the chatbot works great for me, there might still be some bugs lurking inside. I have done my best to address them, but if you encounter any issues, please let me know!
