Variant Manager in collaborative template

Hi, we are a Design studio in Italy. We use UE5.2.
We are able to use the collaborative template and make very good review with our content, but now we need to use the variant manager.
to import in one file more version of the proposal and switch between them very fast. It works quite well for single users, but we are not able to replicate over network so other
player can see the same switch between geometries.
Can you please help us?
