How to use the @pollyjs/utils.ACTIONS.PASSTHROUGH function in @pollyjs/utils

.on('response', req => {
        responseCalled = true;
        expect(req.action).to.equal(ACTIONS.PASSTHROUGH);
      });

async passthrough(pollyRequest) {
    pollyRequest.action = ACTIONS.PASSTHROUGH;

    return this.onPassthrough(pollyRequest);
  }

import { ACTIONS } from '@pollyjs/utils';

const FORMATTED_ACTIONS = {
  [ACTIONS.RECORD]: 'Recorded',
  [ACTIONS.REPLAY]: 'Replayed',
  [ACTIONS.INTERCEPT]: 'Intercepted',

};

export default class Logger {
  constructor(polly) {
    this.polly = polly;
    this.groupName = null;

  connect() {
    this._middleware = this.polly.server
      .any()
