@Unappu I suggest trying what @Vladimir.v.v had said, and try formatting it, generally, SSDs out of the box are unformated and in raw format,
try to see if you have any spare USB pendrive or SD card,
if you do… try getting a linux image flashed to the SD/USB device, and within linux use gparted to format the SSD,
you can format to exFAT, or EXT4 file formats,
this should allow it to be seen by your android system
in any case if the SSD is not accessible in linux as well, I suggest getting a different SSD,
choose from this list, as most of the Linux recognisable ones are here:
best of luck
