lowercase email

[lucassebe]

I'm trying to set an email with lowercase like:
*(using Cypress.io)

var name = faker.name.firstName('male') + ' ' + faker.name.lastName('male');
var email = faker.internet.email(name);

but the response is always like:
name: 'Deusimar Carvalho';
mail: '[email protected]'

how to set the email to lowercase only?
