Did you tried tempotal fusion?

Hello, I researched about the temporal fusion in bev object detection. Because temporal fusion works well in BEVFormer, did you tried temporal fusion in DETR3D? The main difference between the two is that there is bev feature in BEVFormer, but not in DETR3D. I wonder if temporal fusion will work in the object queries in DETR3D, thanks!
