Roku Streaming Sticks are controlled by Roku remotes that connect via WiFi. They are intended for use behind the TV set where infrared (IR) cannot reach, so they are not even equipped to receive IR commands as from Universal remotes.
The only compatible remotes are the three Roku Voice Remote models shown on this page: https://www.roku.com/products/accessories.
You can purchase directly from Roku or from retailers like Amazon, Wal-Mart, Best Buy, etc.
