How to add Bunyan logger in NestJs for logging - node.js

Question

I am trying to add Bunyan logging library in my NestJs application. I am using nestjs bunyan official npm package which is npm i nestjs-bunyan but it's showing error when I am trying to instantiate inside service class. I am using its documentation and taken reference from here https://www.npmjs.com/package/nestjs-bunyan
Below is my code:
app.module.ts
import { Module } from '#nestjs/common';
import { BunyanLoggerModule } from 'nestjs-bunyan';
import { AppController } from './app.controller';
import { AppService } from './app.service';
#Module({
imports: [BunyanLoggerModule.forRoot({
isGlobal: true,
isEnableRequestLogger: true,
bunyan: {
name: 'MyApp',
},
}),],
controllers: [AppController],
providers: [AppService],
})
export class AppModule {}
app.controller.ts
import { Controller, Get } from '#nestjs/common';
import { BunyanLoggerModule, ReqLogger } from 'nestjs-bunyan';
import { AppService } from './app.service';
#Controller()
export class AppController {
constructor(private readonly appService: AppService) {}
#ReqLogger() private readonly logger: BunyanLoggerModule
#Get()
getHello(): string {
return this.appService.getHello();
}
}
app.service.ts
import { Injectable, Logger } from '#nestjs/common';
import { BunyanLoggerModule } from 'nestjs-bunyan';
#Injectable()
export class AppService {
#Logger() private readonly logger: BunyanLoggerModule //Showing red line below #Logger()
getHello(): string {
return 'Hello World!';
}
}
How can I resolve this?

From the npm page it looks like that BunyanLoggerModule type should just be Bunyan, presumably from the bunyan package. Otherwise, you could call it Logger from #nestjs/common
