Unity Third Person Starter Assets unable to change monobehaviour to networkbehaviour for multiplayer integration

Hi. I am attempting to use the thirdpersoncontroller unity starter asset to build a multiplayer game. To do this I need to change monobehaviour to networkbehaviour. It won’t let me make any changes to this and it seems like the Unity.Netcode namespace or whatever it is called is not recognized by the script. I am using it on other scripts and I have the proper package installed “Netcode for Gameobjects”.

I believe the reason for this issue is that whenever I import the starter assets they don’t go into my assets. Instead they import into the packages section underneath assets. I’ve tried moving it out and when the script gets brought up to the assets section it allows me to make the changes I need to make. But this also breaks the script because it relies on other things in the starter assets folder that I cannot bring out of the packages.

Every tutorial I have seen on the asset shows it properly in the Assets folder but mine always imports directly into the Packages folder.

I probably messed something up while importing and I tried my best to explain the issue. Please help me fix this!!!
