ULEZ Expansion Files Oct 2021

Can anyone provide a link to get the ULEZ expansion zone boundaries (October 2021) data file?

TFL points us to their data store: http://roads.data.tfl.gov.uk/
But UX/UI is non existent and it is just an unending list of files with no search ability or anything.

I’ve tried using tfl contacts on site and various other emails I found - radio silence
Many thanks
