                                  </argument>
                      </action>
          </massaction>
         </listingToolbar>
</listing>
</pre>

Once the mass actions is listed, now you need to specify the code that performed on click of that action. To add your custom action, you need to create ‘Massaction.php’ file at below path along with custom action code.
app\code\Vendor\Extension\Ui\Component\Massaction.php

<pre class="lang:default decode:true">

          $badgeColl = $this->collectionFactory->create();
          
          if(!count($badgeColl)){
             return $this->options;
          }

                       [$this->paramName => $optionCode['value']]
                       );
             }
 
             $this->options[$optionCode['value']] = array_merge_recursive(

          }
                     
          // return the massaction data
                     $this->options = array_values($this->options);
          }
          return $this->options;
         }
 
         /**
         * Prepare addition data for subactions
         *

         */         protected function prepareData()
         {
          
          foreach ($this->data as $key => $value) {
          switch ($key) {

          }
         }

You can even add more event actions to ‘Massactions.php’ file as per your need by customizing this code.
