Add new field in create/edit customer backend form

[Jeisson Gomez]

I am working on PrestaShop version 1.7.6.5 and I have added a new column in the customer table of the database, but I have not managed to add the new field to edit the information in the backend of the system. How can I add these fields to the form?
PS: At the moment I am in the file "\src\PrestaShopBundle\Resources\views\Admin\Sell\Customer\Blocks\form.html.twig" where the form template is located, but I add the field (lines 60:62) and it generates an error when run the project.
