How to let a character wait before playing the first animation

My game starts with a matinee cutscene and after the cutscene of about 20 seconds, a character (not the player) comes into the scene and play its custom animation sequences. There is no need for idlewalkrun state for that character because every action is animated in chronological order and the coordinates are right. How can I let the animation play after that 20 seconds but not immediately when the game starts? (probably in animation blueprint?)
