My back wheel on my Giant ATX 2 2019 is wobbly, so I am trying to adjust it. I saw many videos on how to do this. For example, but none of them feature the type of hub that I have. It seems like an axle and skewer in one part (see photos below)
My question is: how to adjust this particular type of hub? Also, what is this type of hub called?
this is how the wheel looks like without the axle:
