Editing model in Blender instantiates new GameObject instead of updating existing one

[user202409]

Reproduction steps:

1. import a model via .blend file into Unity
2. create an empty GameObject "MyScene" in the scene
3. instantiate the imported model as child of "MyScene" using the editor
4. add the MeshSyncServer GameObject to the Unity scene
5. select "MyScene" as root for MeshSyncServer
6. open the imported .blend file in Blender
7. enable "auto sync" in blender
8. edit the model in blender

Expected behaviour:
The instance of the 3d model which is already in the scene is updated.

Actual behaviour:
Another instance is created with this new instance being updated.

Used software:

• Windows 11
• MeshSync 0.17.3-preview
• Unity 2023.2.20f1
• Blender 3.3.6
