About one-time MTX transfer from one linked account to other.

Considering that I have been waiting for a response from the support service for the past two weeks, I decided to post here in the hopes that those who have previously used the MTX transfer feature from one account to another can help clarify the situation for me.
I have a main account on PC and a secondary account that was created for use on Xbox. I haven't played on Xbox for a long time and had a significant amount of MTX points left there. When I realized that these points were not transferable, my only option was to transfer them from my PC to my Xbox account. Over the past 12 years, I've accumulated quite a bit of MTX.
My question is, exactly what is being transferred? I understand that points cannot be transferred. What about other items such as effects, decorative items, items from the Kirak Pass, character frames, forum icons, and so on?

did you ever get a reply? I got replies at first than they stopped.

ive been waiting since Nov 21st for my mtx transfer from xbox to pc its been like 75+ days waiting
