I can't load the character after pressing start the game in the plugin

When I create a new third person project, the default modes setting is as in the first image, and when I start the game, the thirdPersonCharacter spawns, I can control it. For the plugin system, I created a game mode and player controller as in the second image. When the game starts, no characters spawn. For this, do I need to add something to my player controller in the third image? If so, what should I add?
