Access token refresh not work correctly

Problem/Motivation

Sometime we got token error, coz refresh fun on preprecces didn't run

Steps to reproduce

Create webform and attach b24 integration
For some reason token refresh on preprocess func not work correctly and we got error like this one:
Bitrix24 method «crm.lead.add» error: The access token provided has expired..

Proposed resolution

Is it better to check token before request is send?
In the current solution we have a service with the method 'get':

      $request = $this->httpClient->get($uri);
      $this->refreshAccessToken();
      return Json::decode($request->getBody());

So we send a request and after that refresh token each time. My purpose: update token before request is send or check token expired time inside service get method:

      $this->refreshAccessToken();
      $request = $this->httpClient->get($uri);
      return Json::decode($request->getBody());

  $expires = \Drupal::state()->get('b24_token_expires');
  $current_time = \Drupal::service('datetime.time')->getCurrentTime();
  if (($expires - $current_time) < 1800) {
    $this->refreshAccessToken();
  }
  $request = $this->httpClient->get($uri);
  return Json::decode($request->getBody());

It makes sense coz probably we don't need refreshed tokens after request
