Confidence output with TLT Infer on FasterRCNN Model

I currently have several trained fasterRCNN models that I want to do TLT Inferencing and extract the confidence scores for each image. I currently have it displaying the bbox and score on the image itself but I cannot seem to get it to output confidence scores to a txt or json file.

Please refer to [urgent] How to save the bbox confidence probability (i.e. prediction score) during faster-rcnn inference?
