Map Openlanev1 with waymo

I am working on a project where I need the additional data from waymo open data set as well. As, you created OpenlaneV1 from waymo, I was looking to use waymo v1.4.3 data. I manged to map the segments accordingly but I am not finding any way to map the frames of each of the data set. Is it using `frame.timestamp_micros` ?
