Nvme support isn't as great as I'd hoped on my 2014 MBP either. If you don't see it to do this, then you have a bad adapter probably and should buy the one that's most recommended. Click on the gear or down arrow and show all devices in the left side are of disk utility and see if you can then see the nvme, click on the very root of the drive not a volume and format it to apfs. A bare unformatted drive is usually not shown especially in High Sierra+ where they introduced APFS because of the new file structure. Make sure in disk utility you have shown all disks/drives/volumes and not just volumes as is the default view.
