Electron app, How to set the release server URL, only for download app update

Question

I am new to ElectronJs and I am using electro-updater package to publish the app and to fetch app update. I have configured as per the document and current the checkForUpdate method is getting an update from S3 bucket for now, but I need to change it to HTTPS URL so in future checkForUpdate method should call the URL and not the S3 bucket.
