The app cannot be opened safely

[Liklei]

**macOS version: 11.0.1
**Kap version: 3.3.2

Steps to reproduce

1. I'll package and use this package.json
2. run command line - "yarn run dist"
3. The generated DMG files need to be placed on OSS，and then download it locally
4. The Mac's security and privacy preferences are set to allow the installation of apps from the App Store and approved developers

Current behaviour

The system told me that I couldn't develop the APP because I couldn't verify the developer.Buttons only move to the wastebasket and cancel

Expected behaviour

We're hoping for the following:
Prior to macOS Catalina, opening an app that hasn't been notarized shows a yellow warning icon and asks if you're sure you want to open it:

const fs = require('fs');
const path = require('path');
const electron_notarize = require('electron-notarize');

module.exports = async function (params) {

        return;

    let appId = '***'
    let appPath = path.join(params.appOutDir, `${params.packager.appInfo.productFilename}.app`);

    if (!fs.existsSync(appPath)) {
        throw new Error(`Cannot find application at: ${appPath}`);
    }

    try {

Why are you packaging Kap yourself? We already provide a packaged version of the app.

I know , I just wanted to give it a try

We cannot really provide general Electron support here. Packaging works for us, so it must be something with your system.
