OpenAI Assistant help

Hi Type Bot Community!

I need a bit of help with the OpenAI Assistant settings in the simple typebot template. I have configured my OpenAI account, and it sees my assistant, but when I test the integration, it doesn't seem to be aware of the files that I have uploaded to the assistant.

Effectively I need to be able to pass in a block like the following:

{
"assistant_id":"asst_xxx"
"additional_instructions":NULL
"tool_choice":{
"type":"file_search"
}
}

I'm trying to pass this in through the messages block like the following attached image. Is this the right way to do this?

Thanks!!
