How can I import OpenTelemetryModuleOptions, OpenTelemetryOptionsFactory interfaces?

Expecting Behaviors

I want to configure OpenTelemetryModule with forRootAsync({ useClass: ... }) method by utilizing nestjs/config.
But, it seems that nestjs-otel package is not exporting OpenTelemetryModuleOptions, OpenTelemetryOptionsFactory interfaces.

    OpenTelemetryModule.forRootAsync({
      useClass: OtelConfigService
    }),

import { Injectable, Logger } from '@nestjs/common'
import { ConfigService } from '@nestjs/config'
import { OpenTelemetryOptionsFactory, OpenTelemetryModuleOptions } from 'nestjs-otel';

@Injectable()
export class OtelConfigService implements OpenTelemetryOptionsFactory {
  private readonly logger = new Logger(OtelConfigService.name)

  constructor(private configService: ConfigService) {}

  createOpenTelemetryOptions(): Promise<OpenTelemetryModuleOptions> | OpenTelemetryModuleOptions {
    const { hostMetrics, apiMetrics } = this.configService.get('otel')

    return {
      metrics: {
        hostMetrics: hostMetrics.enabled,
        apiMetrics: {
          enable: apiMetrics.enabled,
        },
      },
    };
  }
}

Version is 6.1.1.
How can I use forRootAsync({ useClass: ... }) with your suggested constant value?
Is there any example code?

I'm working on my first Nest.js project, so I don't know much about it yet. 😂
