The Express 4M2 enclosure only works with NVMe (PCIe 3.0) SSDs. SATA M.2 drives will not function if installed.
Note that you cannot distinguish an NVMe M.2 drive from a SATA-based drive just by looking at the M.2 connector key. Both types of drives can utilize the M-key style connector required by this enclosure. Therefore the only way to verify the M.2 drives are the correct type, is to make sure the specifications and/or packaging specifically mention the use of NVMe and an M-key connector.
Note also the required M.2 form factor is "2280" (i.e. 22mm wide x 80mm long).
