Change the nozzle

Hi. This is my first IDEX printer, and first direct drive printer as well, with a MK8 nozzle. My other printer is very different.
Please, I need to learn how to change the nozzle of ths SV04. I know it is very basic, but I could not find a video made for this specific printer. Thank you.
