Hi Barb,
Thank you, it works!
Notes:
I've encountered 2 problems which seem to be on the Godot's side.
1: After exporting and opening the Godot editor, the addon doesn't have the option to choose the "level" folder.
At this moment, just restart the editor, and the option will appear.

2: After that, the exported glb file that contains the Beizer curve object from Blender, needs to be re-imported. Otherwise, it will still appear as a mesh when it is opened in the scene.
(even if it shows as a Path3D object when one is viewing the glb file)
(I'm using Godot_v4.2.1-stable_win64, Blender 3.6.5)
Also, note the spelling:
