How to release the electron app with only modified modules/files?

Question

I am using electron builder to package the app and releasing on github private repository and also implemented electron-updater to update the app automatically in background, everything is working fine.

but the problem is each time i am releasing the app on github using below script

"scripts": {
      "deploy": "electron-builder --config=electron-builder.yml build --win --x64 --ia32 --publish always" 
 },

Electron-builder config file

  output: dist
  buildResources: build

electron builder always creating new package/installer/app with same size[in between 250-300MB] and electron updater is downloading the updated version of app.

So how can i reduce the size of progressive releases[or release only modified module/files] because its very frustrating to download complete app each time.

I have tried compression[not getting much difference] and removed some unused packages as well. As i know VS Code/ Zoom/ Slack are managing this scenario but i don't know how.

I need some help/direction to achieve it. Thanks in advance.

Mate that's not possible at the moment. I request you to follow the common approach of bundling new application and make release.
