Do you know where we can find information about this module?

Saw that. That is not enough information to be useful for our purpose.
Try this: (you will probably have to try guessing which lead is which. Of course that module might not only be a transistor.

How did you find that????
Given that this is not a bipolar transistor, there is no reliable way to check it with a DVM other than to check for shorts between the drain to source and between the gate and the drain and the gate to source. Beyond that you need to vary the gate-to-source voltage while observing the drain-to-source resistance. That would give you a pretty good check.
