How update a webform submitted value clicking in a button?

Question

How can I update a submitted data just clicking in a button? I have created a View table of webform subissions and I would like to add a collumn with a button "Aprroval". When user click on this button, the data value must be updated. My intention is optimize the "edit" and "save", avoiding the Form edit screen. Add a custom action in a "Webform submission operations bulk form" solves my problem too.

You can use hook_entity_operation to add a custom entity operation for webform submissions. With the Webform Views Integration module you should already be able to add an "Operations" field to your view. It lists the default operations depending on access levels (Edit, Delete etc.). There your custom operation will appear.

MYMODULE.module

<?php

/**
 * @file
 * Hooks implemented by the MYMODULE module.
 */

use Drupal\Core\Entity\EntityInterface;
use Drupal\webform\WebformSubmissionInterface;

/**
 * Implements hook_entity_operation().
 */
function MYMODULE_entity_operation(EntityInterface $submission) {
  $operations = [];
  if ($submission instanceof WebformSubmissionInterface) {
    if ($submission->getElementData('MY_HIDDEN_REVIEW_ELEMENT') !== 'approved') {
      $operations['approve'] = [
        'title' => t('Approve'),
        'weight' => 15,
        'url' => Url::fromRoute('MYMODULE.webform_submission_approve', [
          'submission' => $submission->id(),
        ], [
          'query' => \Drupal::destination()->getAsArray(),
        ]),
      ];
    }
  }
  return $operations;
}

MYMODULE.routing.yml

MYMODULE.webform_submission_approve:
  path: '/admin/MYMODULE/submission/{submission}/approve'
  defaults:
    _controller: '\Drupal\MYMODULE\Controller\WebformSubmissionApproveController::approve'
  options:
    parameters:
      submission:
        type: 'entity:webform_submission'
  requirements:
    _custom_access: '\Drupal\MYMODULE\Controller\WebformSubmissionApproveController::access'
