Loader doesn't work, but plugin does

[Karmalakas]

What am I missing? I have this config under module.rules:

                {
                    test: /\.js$/,
                    exclude: /node_modules/,
                    enforce: 'post',
                    use: {
                        loader: WebpackObfuscator.loader,
                        options: {
                            debugProtection: true,
                            disableConsoleOutput: true,
                            rotateStringArray: true,
                            selfDefending: true,
                        }
                    }
                }

And it doesn't obfuscate. But if I use it as a plugin:

            new WebpackObfuscator({
                debugProtection: true,
                disableConsoleOutput: true,
                rotateStringArray: true,
                selfDefending: true,
            }),

Then it works just fine 🤔

    "javascript-obfuscator": "^3.0.0",
    "webpack": "^5.65.0",
    "webpack-obfuscator": "^3.5.0"

Same with:

    "javascript-obfuscator": "^4.0.0",
    "webpack": "^5.73.0",
    "webpack-obfuscator": "^3.5.1"

In my case, none of these work. Neither loader, nor plugin.
