Query to identify the unblurred videos

Hello,
I am a privacy researcher and I want to perform some egocentric blurring on the clear videos, you mentioned this in the docs:

In total, 612 hours of the EGO4D dataset contains video where participants consented to remain unblurred.

The problem is I don’t know how to get the video IDs of those 612 hours, I couldn’t find any tag that mentions unblurred.

Cheers.
