Importing Parented Object From Blender

Hi, I am having an issue with importing parented objects (eyes) from Blender. Those objects are parented to the armature of the body, and they move perfectly well as I intended in Blender. However, when I export them to Unity, they are no longer moving along with their parent (armature).

I tried the methods written on this post but they didn’t work for me.), but it didn’t work. Does anyone have a good idea of how I can solve this issue?
