Installing ionCube with ftp

[Demow]

Hello everyone, I am using the WordPress hosting package on GoDaddy. However, I have two-step verification in my account and my phone number is lost. That's why they are not providing support to me. I have installed a new theme, but my site is not opening because it lacks ionCube.

ERROR: Site error: the ionCube PHP Loader needs to be installed. This is a commonly used PHP extension for running ionCube protected PHP code, website security, and malware blocking. Please visit get-loader.ioncube.com for installation assistance.

I only have access via FTP, and despite researching online, I couldn't do it. Can you help me with the simplest way to do this task?
