How to use the @aws-cdk/aws-logs.LogGroup function in @aws-cdk/aws-logs

public bind(scope: Construct, containerDefinition: ContainerDefinition): LogDriverConfig {
    this.logGroup = this.props.logGroup || new logs.LogGroup(scope, 'LogGroup', {
        retention: this.props.logRetention || Infinity,
    });

    this.logGroup.grantWrite(containerDefinition.taskDefinition.obtainExecutionRole());

    return {
      logDriver: 'awslogs',
      options: removeEmpty({
        'awslogs-group': this.logGroup.logGroupName,
        'awslogs-stream-prefix': this.props.streamPrefix,
        'awslogs-region': Stack.of(containerDefinition).region,
        'awslogs-datetime-format': this.props.datetimeFormat,
        'awslogs-multiline-pattern': this.props.multilinePattern,
      }),
    };
  }

addLogGroup(logGroupName: string) {
    const retentionDays = Infinity
    const props = { logGroupName, retentionDays, retainLogGroup: false }
    return new LogGroup(this, `${this.id}-${logGroupName}`, props)
  }
