Cannot use voice command to switch input

TCL 65R617  Roku ver 8.12 build 4024 - I can press the microphone button on the remote and just say "Antenna" and it will switch to the antenna. But if I say “switch the input to HDMI 1” from Home screen per the example in the link below, it states that it cannot help. If I try it while watching OTA off Antenna, it states that voice is not currently available.
No matter which input name I rename it to, it will not switch.
