Cant get control over second player

Hello everyone. I’m trying to test multiplayer prototype. I followed this lessons Unreal Engine 4 C++ Networking Part 1 - YouTube . And it seems that the author gains control over the player when related window gets focus. When i click play in new editor window, only one of the characters receives input, and only if its window is in focus. the other character doesnt receive input, no matter whether its window is in focus or not. I found many answers on similar questions, but neither helped. also i have no gamepad, so i can’t even try to control other character with it. How can i switch control between characters in testing purposes? I dont need to switch control during gameplay.

P.S. if there was some grammar mistakes in this question, please forgive me my bad english =))
