How can I get the customer increment ID in an observer in Magento2 if using the human friendly ID

I am trying to get a magento customer increment ID. I’m thinking I have to use the resource-model class just not sure what the best way to access it is or how to get it.

 public function __construct(

        MagentoCustomerApiCustomerRepositoryInterface $customerRepositoryInterface,
        MagentoCustomerModelResourceModelCustomer $resourceModel,

    )
    {
        parent::__construct();
        $this->customerRepo = $customerRepositoryInterface;
        $this->customerResource = $resourceModel;
    }

    protected function execute(
        InputInterface $input,
        OutputInterface $output
    )
    {

            $email = 'email@email.com'
            $data =  $this->customerRepo->get($email);
            $cid =  $data->getId(); //checking exists
            $rsrd= $this->customerResource->loadByEmail($data,  $email);
            $incrementid =  $data->getAttribute('increment_id');


            $output->writeln( 'email: ' . $email . ' customer id: ' . $incrementid );
        }
    }
