How exactly do I apply my custom transforms/scale in object-level? I literally just downloaded Blender yesterday so I could change the size of the cube lmao! I know nothing about this

I downloaded a game mode featuring a rotating cube. After editing the code to make it better I went into Blender and made the cube bigger, but it somehow loads the original cube even though the file has been replaced with the modified one. I even made a new server and tried to host the game mode - same issue. What is going on here?!
