How to configure neoconf.nvim to autocomplete for installed plugins?

Question

I'm currently writing a lua plugin and I can't figure out how to get neconf.nvim to autocomplete the library methods. This is my .neoconf.json file

{
  "neodev": {
    "library": {
      "enabled": true,
      "plugins": [
        "plenary"
      ]
    }
  },
  "neoconf": {
    "plugins": {
      "lua_ls": {
        "enabled": true
      }
    }
  },
  "lspconfig": {
    "sumneko_lua": {
      "Lua.runtime.version": "LuaJIT",
      "Lua.workspace.checkThirdParty": false
    }
  }
}

I'm using LazyVim and I tried to make sure that neoconf.nvim and neodev.nvim were install properly, but autocomplete is still not working for installed plugins.
