How to prevent Chat Attachments Reader to read previous attached files in the same session

Summary:

HiI am developing an AI Agent with the following use case:

The agent should accept two CSV files as attachments and compare the contents of the two files. If only one file is attached, the agent should display the message: "Provide two valid files." If two valid files are attached, the agent should display: "Files are Valid."

The current workflow works as follows:

1. Attach a valid CSV file using the chat experience.
2. The agent responds with "Provide two valid files."
3. Attach two CSV files: one valid file and one invalid file.
4. The expected result is "Provide two valid files."
