How to recreate nnoremap behaviour

[quackerex]

I want to recreate this behaviour in VSCodeVim.

nnoremap <C-d> <C-d>zz
nnoremap <C-u> <C-u>zz

[quackerex]

Add these to normalModeKeyBindingsNonRecursive

    {
      "before": ["<C-u>"],
      "after": ["<C-u>", "z", "z"]
    },
    {
      "before": ["<C-d>"],
      "after": ["<C-d>", "z", "z"]
    },
