Filter customer collection by custom attribute in magento 2

I created a custom attribute for customer and would like to filter my collection through it.

My UpgradeData:

if (version_compare($  context->getVersion(), '1.0.6', '<')) {      $  attributesInfo = [         'celular'  => [         'label'    => 'Celular',         'type'     => 'varchar', // can be static too         'input'    => 'text',         'unique' => true,         'position' => 90,         'visible'  => true,         'required' => true,         'system'   => 0, // Important otherwise attribute is not seen as custom attribute     ], ];      foreach ($  attributesInfo as $  attributeCode => $  attributeParams) {         $  customerSetup->addAttribute(\Magento\Customer\Model\Customer::ENTITY, $  attributeCode, $  attributeParams);     }      foreach ($  attributesInfo as $  attributeCode => $  attributeParams) {          $  attribute = $  customerSetup->getEavConfig()->getAttribute(\Magento\Customer\Model\Customer::ENTITY, $  attributeCode);         $  attribute->setData(             'used_in_forms',             ['adminhtml_customer']         );         $  attribute->save();     } } 

My Collection:

$  objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $  customerObj = $  objectManager->create('Magento\Customer\Model\ResourceModel\Customer\Collection');          $  customer = $  customerObj->addAttributeToSelect('*')         ->addAttributeToFilter('celular',$  username)         ->load()->getData(); 

Even though I am attaching a value to this field, no customer is found, what should I do?
