Upload files while chatting with an AI Expert

would love the ability to upload files in the chat of AI Expert to get feedback and responses based on the data uploaded which is in line with the backend foundation of data for that particular AI Expert

Eg: I have made an AI Expert which is linked to Community guidelines, I use it to verify my activities if they are in line with our community goals and values. I wanted to add a ppt from a solo creator in to check if it is in accordance with the same.
