Generate electron app.exe which will ask for user input during installation (using electron-builder and nsis)?

I am trying to generate electron app.exe with the use of **electron-builder** and **nsis**, which should ask user input at time of installation.

Following is my **package.json**.
...
"build": {
    "appId": "com.electron.test",
    "productName": "test",
    "win": {
      "target": [
        "nsis"
      ],
      "icon": "assets/icon.ico"
    },
    "nsis": {
      "warningsAsErrors": false,
      "installerIcon": "assets/icon.ico",
      "runAfterFinish": false,
      "oneClick": false,
      "perMachine": true,
      "allowToChangeInstallationDirectory": true,
      "installerHeader": "assets/installerHeader.bmp",
      "include": "build/installer.nsh"
    },
    "mac": {
      "category": "your.app.category.type"
    }
}
...

I want to display custom page **Between** Select Location Page and Installation Progress Page.
Following is my **installer.nsh** which is create one custom page i.e. ask for user to input username and password.


!include "EnvVarUpdate.nsh"
!include "MUI2.nsh"
!include "nsDialogs.nsh"
!include "LogicLib.nsh"

Var Dialog
Var UserLabel
Var UserText
Var UserState
Var PassLabel
Var PassText
Var PassState

Function nsDialogsPageLeave

    ${NSD_GetText} $UserText $UserState
    ${NSD_GetText} $PassText $PassState

    ${If} $UserState == ""
        MessageBox MB_OK "Username is missing."
        Abort
    ${EndIf}

        MessageBox MB_OK "Password is missing."
        Abort
    ${EndIf}

    StrCpy $1 $UserState

    FileOpen $9 $INSTDIR\credentials.txt w
    FileWrite $9 "$1:$2"
