Howto: call snippets with vscodevim keybindings?

[sql-koala]

Hi, can another help me with this? I want to create keybindings to call snippets from visual mode.
I start with an example from here: https://code.visualstudio.com/docs/editor/userdefinedsnippets

{
  "key": "ctrl+k 1",
  "command": "editor.action.insertSnippet",
  "when": "editorTextFocus",
  "args": {
    "langId": "sql",
    "name": "min"
  }
}

(I tested this ^^ call, it works).

Here is an example that shows a keybinding calling a vscode command with args. But I could not adapt it.
https://github.com/VSCodeVim/Vim

"vim.visualModeKeyBindingsNonRecursive": [
        {
            "before": [
                "<leader>", "v", "i", "m"
            ],
            "commands": [
                {
                    "command": "git.clone",
                    "args": [ "https://github.com/VSCodeVim/Vim.git" ]
                }
            ]
        }
    ]

Any help? My experience with json is copy + paste + try ;-)

I'll leave this open for a few days to see if i get help.
