Is this uNet? That is outdated… check the date on the videos you are watching.
My best suggestion is to buy Invector Basic (or Melee) plus Easy Multiplayer for Invector. Might cost $70-90 but you will have a working product similar to the videos you were watching since Mirror is based on old uNet.
However, Mirror is not good for beginning programmers at all. You should really get a Photon PUN2 example project that is working and modify it to do what you want.
