How to locate docker drive location on WSL2

When I run docker inspect mysql:

"Mounts": [            {"Type": "volume","Name": "backend_sql","Source": "/var/lib/docker/volumes/backend_sql/_data","Destination": "/var/lib/mysql","Driver": "local","Mode": "rw","RW": true,"Propagation": ""            }        ],

I don't have /var/lib/docker/volumes in my WSL2 (not even as root).
When are the named volumes location?
