Custom textarea editor

Question

I would like to transform the default textarea editor in my custom admin module with this module : https://github.com/Magenerds/PageDesigner

It is a module to create responsive content with CMS et block, it is perfectly working. Demo: https://www.youtube.com/watch?v=E0wZzVPFhM0

Now, I need to use this functionnality in my custom module, I tried to modify the di.xml file to modify the behavior of my module, not result.

Default di.xml:

<?xml version="1.0"?>
