General How to unpack KN5 driver model?

[handsoappp]

I'm want to unpack the driver model from Assetto Corsa and put it into blender. However, I'm not sure how to do this because the sidebar that usually shows up in the showroom to unpack car models isn't there.


*What I see when I open up the cm showroom

BTW, the driver model is opened via the content > miscellaneous > driver models.

Any kinds of help will be appreciated!
