How to move the cursor to a specified position after selecting autocomplete suggestion in the ace editor?

I have created the following custom string for autocomplete in the ace editor.

{
  "\\sin{$1}",
  "\\cos{$1}",
  "\\tan{$1}",
  ...
}

I want to move the cursor position, after selecting this autocomplete suggestion, to the specified location. In the example above, I want to move the cursor to the position marked $1.

The image I have is a feature like the one in the user snippet in Visual Studio Code.If you write "$1" in the string of the registered snippet, the cursor will move there after selecting an autocomplete suggestion.

"Print to console": {
    "prefix": "log",
    "body": [
        "console.log('$1');",
    ],
    "description": "Log output to console"
}

Could you please suggest me how can I implement this?

Thanks in advance
