Creating an Arch Viz with CRM application integration inside Unreal Engine ?

Hello Everyone,

I hae a project where we need to create a digital twin for a housing compound, and the client wants us to create the whole experience inside Unreal Engine, where the users will use this software on high-end PCs, but the issue is that the system must be integrated with a CRM application that will be used on mobile devices and IPads, and as the user modifies the scene data on the application, these modifications will reflect on the Unreal Engine application on the PCs.

The question is: are there any tools or plugins to make this process easier to implement? and if not, where can I start learning how to do such a solution ?

This video is a bit similar to the thing I’m after, I hope that it clarifies my idea better.

Thank you for your help guys!!
