Class "App\Models\BlindIndex" not found issue

[grafxflow]

I am getting the following error when trying to update the users emails.

php artisan ciphersweet:encrypt "App\Models\User" <CIPHERSWEET_KEY>

 Class "App\Models\BlindIndex" not found

The only way I have found to sort this is changing the code to the following.

public static function configureCipherSweet(EncryptedRow $encryptedRow): void
{
     $encryptedRow
     ->addField('email')
     ->addBlindIndex('email', new \ParagonIE\CipherSweet\BlindIndex('email_index'));
}

Is there something I am missing?

I've been trying this locally in laragon environment. I found that I needed to do as you pointed out below. After I did this, however I got the following exception:
Uncaught SodiumException: Not using the native libsodium bindings

What I found fixed this, was making sure that the sodium extension is enabled for php. Restart apache and it worked. For anyone that encounters the same issue.

Adding use ParagonIE\CipherSweet\BlindIndex;to the top of the file worked for me.
