def file_uploader():
    # Allow users to upload multiple image files of specified types
    uploaded_files = st.file_uploader("Please upload conversation images!", accept_multiple_files=True, type=["png", "jpg", "jpeg"])
    
    if uploaded_files is not None:
        # Save uploaded files in session state
        st.session_state.uploaded_files = uploaded_files
        # Set the number of images to display in one row
        num_columns = 3
        cols = st.columns(num_columns)
        
        for i, uploaded_file in enumerate(uploaded_files):
            image = Image.open(uploaded_file)
            ocr_prompting(image)  # Call the OCR function
            # Select the column to display the image
            col = cols[i % num_columns]
            col.image(image, caption=uploaded_file.name)
            
    else:
        st.session_state.uploaded_files = []
        st.session_state.ocr_result = []

I’m trying to extract text from images using GPT API’s OCR function, and I’m currently configuring the UI with dummy data.

However, when I upload a file through st.file_uploader, it shows a list of files like below and if I press X, it will be deleted, right?

I want to manage session_state with this button, is there any way?
