Typescript: Exporting Enum classes to JS produces compilation error-CodePudding

I trying to export Kotlin Enum classes to JS

@OptIn(ExperimentalJsExport::class)
@JsExport
enum class interEnum {
    SAMPLE
}

But in Angular Project, after importing as NPM module, the respective TS block in module_name.d.ts throws error during compilation when trying to run.

abstract class interEnum { // exported from Kotlin/JS 
    private constructor();
    static get SAMPLE(): com.example.demoapp.interEnum & {
        get name(): "SAMPLE";
        get ordinal(): 0;
    };
    static values(): Array<com.example.demoapp.interEnum>;
    static valueOf(value: string): com.example.demoapp.interEnum;
    get name(): "SAMPLE";
    get ordinal(): 0;
}

tsconfig.json:

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es2015",
    "module": "es2020",
    "lib": [
      "es2018",
      "dom"
    ]
  }
}

Error from ng serve:

294 }

What are these errors ? Since I am new to JS and TS, I can't understand this. The editor not showing any errors.

If I remove the get keywords, then it's compiling successfully.

I can't understand what's wrong here. Please help me

According to the official documentation for 1.7, it is prohibited to export enum classes.

This link provides some useful tips for exposing enums to TypeScript.
