Issue with the Neewer NW700 Microphone

Hello.
I recently acquired a Neewer NW-700 (https://www.amazon.fr/Neewer®-NW-700-Microphone-Condensateur-Suspension/dp/B00XOXRTX6) which is a condenser microphone that unfortunately doesn't work on my computer (with the provided XLR to mini jack cable). In the documentation, they basically say that my sound card is a 3-volt card while a 5-volt one is needed.

I tested it on a guitar amp, and it doesn't work there either, and now I'm really confused.

The documentation states that if the sound card isn't powerful enough, I need to use phantom power, but I don't really want to buy one.

I have a Behringer DJX900 USB mixer and would like to know if it has built-in phantom power (since there is an XLR input for a microphone) and/or if the NW700 works with it.

Just to see if it’s worth buying a male to female XLR cable to connect the microphone to the mixer.

Or if you have a solution, I'm open to suggestions.

P.S.: I tried increasing the gain in Windows sound settings: it sounds terrible.
