USB drives visible but do not show up in file browser

I have a couple of SanDisk USB drive. I have a dual boot Ubuntu 22 / Windows 10 Lenovo laptop and these USB drives work as expected when booted in Windows, and they also work fine in my MacBook, so it is not an issue with the drives themselves.

The drives are recognised when I plug them in :-

lsusb | grep -i sandiskBus 003 Device 006: ID 0781:5581 SanDisk Corp. Ultrasudo dmesg | grep -i sandisk[ 1232.508559] usb 3-6: Product:  SanDisk 3.2Gen1[ 1233.528479] scsi 6:0:0:0: Direct-Access      USB      SanDisk 3.2Gen1 1.00 PQ: 0 ANSI: 6

And from sudo fdisk -l

Disk /dev/sdc: 14.32 GiB, 15376318464 bytes, 30031872 sectorsDisk model:  SanDisk 3.2Gen1Units: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisklabel type: dosDisk identifier: 0x0008b1c4Device     Boot Start      End  Sectors  Size Id Type/dev/sdc1  *     2048 30031871 30029824 14.3G  c W95 FAT32 (LBA)

But they do not show up in the file browser.I think that I am missing a driver or something?
