Type 'aspose.words.saving.IPageSavingCallback' is not an acceptable base type

I am evaluating aspose-words python version v23.1. I want to set page_saving_callback in PdfSaveOptions. But I got the exception:

TypeError: type 'aspose.words.saving.IPageSavingCallback' is not an acceptable base type


class WordPageSavingCallback(aspose.words.saving.IPageSavingCallback):

    def page_saving(self, args: aspose.words.saving.PageSavingArgs):
        print('test page saving call back')

if __name__ == '__main__':

    document = aspose.words.Document('test.docx')
    options = aspose.words.saving.PdfSaveOptions()
    options.page_saving_callback = WordPageSavingCallback()
    document.save("output.pdf", options)

Any sample source file test.docx can reprodcue the issue.
Please let me know how to write a class inherits IPageSavingCallback.

@yueru Unfortunately, using callbacks in the Python version of Aspose.Words is not supported yet.
