Razer Blade Advanced 21 / SSD Mounting Problem

hi guys, i recenntly bought a blade 15 advanced with the rtx 3070, i7 10875 model 21 and wanted to upgrade my RAM and SSD. A 1TB SSD is already installed and like advertised, i wanted to add a second ssd on top of the already installed one. I, unfortunately dont know how this should work, it seems my ssd is too short (allthough it is a normal 80mm long SSD). Is there a trick ? i watched many videos, but all Razer models i saw had other solutions then mine. In the picture you see that my normal ssd (80mm long) is simply too short to be mounted with the screw, i painted how my ssd fits in if it is put in the slot.
Many thanks in advance from Germany
