How do I make Player 2 react to controls?

I’m making a Hello, Neighbor! mod that adds multiplayer, I have a custom Blueprint character called “Player 2”
It moves just fine when I make it Player 1 in a single player game, when I add “BP_Human” (The game’s default character.) Player 2 can no longer move. What am I doing wrong?

I forgot to mention, the thing is being done on one keyboard for testing purposes.
