detectron2 onnx model "current backend is not supported"

[FahriBilici]

Hello, I trained detectron2 for object detection with my dataset. I exported the model in onnx format. I downloaded onnx.js demo from Github and replaced yolo model path with my custom detectron2 onnx model path. But it gives me a"current backend is not supported" error. How can I fix that?
