How to install additional M.2 SSD storage?

How do I install additional M.2 SSD storage on this PC?

There is suppose to be an available expansion M.2 slot in addition to the existing M.2.SSD (1 TB WD Black PCIe® Gen4 NVMe™ TLC M.2 SSD) that came with the computer when I bought it.

Also, I cannot even locate the existing M.2 SSD (1 TB WD Black PCIe® Gen4 NVMe™ TLC M.2 SSD) on this computer.  Can someone also help me locate it on this computer?

I would read the manual if there is one, but it doesn't seem like HP provides it. If you can help, please help me out. This is my first gaming computer and I would like to upgrade it if I can.

While the picture in the manual is not very specific, it does show the general area on page 8 and 9

Perhaps the reason it is not recognizable is there is a heat shield over it, as depicted on page 20, picture 5 and 6.

And there is another thread concerning the same PC and available M2 slots
