@Abel-Boby, do you see a list of voice commands on this page?
You should have one voice command for each of your triggercmd commands that has a voice word, but only if the computer is your default computer or it has a voice word assigned to it. You can set your default computer on your profile page.
In other words, these are the requirements for creating virtual devices in Google Home for your commands:
Each command must have a voice word.
Each computer must have a voice word, or it must be your default computer.
