Entity Browser module
This module was tested on 7th December 2018, using Drupal 8.6.4 with DX8 5.2 using version 8.x-2.0 of the module.
There are known issues using the Entity Browser with DX8.
When browsing for an image within a DX8 element, it will open IMCE. Currently you can not select which browser to use.
It is on our roadmap to allow the use of Entity browser within DX8 elements.
