Ext4fuse usage to see and browse the volume in Finder

I want to copy some files of my old encrypted SSD with ubuntu. I installed ext4fuse and done sudo ext4fuse /dev/disk3s1 /Volumes/Linux, although I don't know if it is the right partition number (where can I see them in Disk Utility?). **How do I open then the disk in Finder?** Possibly in the "devices" section. I navigated to /Volumes and didn't see Linux (or whatever it is).
