Trying to install second SSD in HP Omen 17" laptop

[MsBarrows]

I have an HP Omen 17" laptop I bought last year. The build available at the time came with a 1TB HDD and a 250gb PCIe SSD boot drive. I replaced the HDD with a 2TB SATA SSD with no problem. Space on the SSD has now gotten low enough that I decided to install a second PCIe SSD.  I purchased a 2TB Crucial PC NVMe PCIe 2280 M.2 SSD, which arrived this morning. I've installed it, but the laptop is failing to recognize it; there is no entry for it in the Disk Management tool.

Have I purchased the wrong type of PCIe drive? Some other possible problem??

Please initiate Crucial drive first. I had to do that for my machine. Please use the following Guide:

Thanks! Some further googling yesterday had led me to a similar solution; my main problem was that it wasn't even showing up in disk management. I followed the diskpart walkthrough to initialize it (where it was showing up, as Disk 0), and after I'd converted  it to  MBR and then back to GPT, and rebooted the laptop again, it finally showed up in disk management and I was able to create a volume on it.
