Now, we will use our tools to insert the new SSD into the available slot. The tools we need are the magnetic screwdriver, one M2 mounting screw, and one M2 screw.

There are empty slots, as circled in the second photo; place an M2 mounting screw into the slot.

After that, place the SSD into its slot and align the head to the mounting screw. Properly screw the SSD into place.
