Marvelous Designer Support

Hi, I'm using MD python API to export garment as obj mesh.

From the python API document, if I provide ImportExportOption, the Export Dialog should not pop up. https://developer.marvelousdesigner.com/list.html 

def ExportOBJ(_filePath : str, _options : ImportExportOption) -> list[str]
"""
@brief Export OBJ file
@param _filePath: output file path
@param options: If "options" is given, it exports OBJ according to options, not allowing user for selecting options in Export Dialog.
@return Output file paths. It outputs the file paths of an OBJ file and multiple MTL files for colorways. If the value "bSaveInZip" in ImportExportOption is true, it outputs a file path of a zipped file. If an error occurs, return empty string. If filePath parameter is not given, output files will be created in CLO temporary folder.
"""

But even though I provide both filePath and ImportExportOption parameters, the Export Dialog still pops up, here is my code

opt = ApiTypes.ImportExportOption()
opt.bExportGarment = True
opt.bExportAvatar = False
opt.bSingleObject = True
ret = export_api.ExportOBJ(obj_file, opt)

Is there any problem in my code, How can I export obj directly without any popups? Thanks!
