Add custom attribute customer

Question

I want to add a custom attribute to my customer. For now I have this : (on magento 2.2.4)

<?php
namespace My\Module\Setup;

use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{

private $customerSetupFactory;
private $attributeSetFactory;

public function __construct(\Magento\Customer\Setup\CustomerSetupFactory $customerSetupFactory, \Magento\Eav\Model\Entity\Attribute\SetFactory $attributeSetFactory)
{
    $this->customerSetupFactory = $customerSetupFactory;
    $this->attributeSetFactory = $attributeSetFactory;
}

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
    $installer = $setup;
    $installer->startSetup();

    /** @var CustomerSetup $customerSetup */
    $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
    $customerSetup->removeAttribute(\Magento\Customer\Model\Customer::ENTITY, "customer_bonus");

    $customerEntity = $customerSetup->getEavConfig()->getEntityType('customer');
    $attributeSetId = $customerEntity->getDefaultAttributeSetId();
    $attributeSet = $this->attributeSetFactory->create();
    $attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId);


    $customerSetup->addAttribute(\Magento\Customer\Model\Customer::ENTITY, 'customer_bonus', [
        'type' => 'varchar',
        'label' => 'Customer Bonus',
        'input' => 'text',
        'required' => false,
        'visible' => true,
        'user_defined' => true,
        'system' => false,
    ]);

    $attribute = $customerSetup->getEavConfig()->getAttribute(\Magento\Customer\Model\Customer::ENTITY, 'customer_bonus')
        ->addData([
            'attribute_set_id' => $attributeSetId,
            'attribute_group_id' => $attributeGroupId,
            'used_in_forms'=>['adminhtml_customer']
        ]);

    $attribute->save();

    $installer->endSetup();
}

}

But there's nothing on my backend, I want have something like this result : Magento 2 - How to add a custom column in customer grid

public function upgrade(ModuleDataSetupInterface $setup, ModuleContextInterface $context)

    $setup->startSetup();
    /** @var CustomerSetup $customerSetup */

    if (version_compare($context->getVersion(), '1.0.1', '<')) {
        $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);

            'unique'    => true,
            'system' => 0,
        ] );

    //add attribute to attribute set
    $attribute = $customerSetup->getEavConfig()->getAttribute(Customer::ENTITY, 'sap_id')
    ->addData([

    ]);

    $attribute->save();
    $setup->endSetup();
   }
