If I want to export ppt as a thumbnail or PDF file, how can I achieve this?
Currently, I am getting a blank object when I try to add Map. Please check the images attached.

for ppt and pdf export:

    presentation.save("sample.pptx",
            slides.export.SaveFormat.PPTX,
        )
        # Instantiates the PdfOptions class
        pdfOptions = slides.export.PdfOptions()

        # Sets the Jpeg quality
        pdfOptions.jpeg_quality = 70

        # Sets the behavior for metafiles
        pdfOptions.save_metafiles_as_png = True
        pdfOptions.sufficient_resolution = 64

        # Sets the text compression level
        pdfOptions.text_compression = slides.export.PdfTextCompression.FLATE

        # Defines the PDF standard
        pdfOptions.compliance = slides.export.PdfCompliance.PDF15
        presentation.save("sample.pdf",
            slides.export.SaveFormat.PDF,
            pdfOptions,
        )

For thumbnail export:

    scale_x = (1.0 / ppt.slide_size.size.width) * 1024
    scale_y = (1.0 / ppt.slide_size.size.height) * 576
    with slide.get_thumbnail(scale_x, scale_y) as bmp:
    	bmp.save("img.png", draw.imaging.ImageFormat.png)
    	return file_name

@anantutkpd,
Please also note that you need to set the slide size for the target presentation to avoid shape misplacing.

...
map_chart = presentation1.slides[0].shapes[0]
presentation2.slide_size.set_size(presentation1.slide_size.type, slides.SlideSizeScaleType.DO_NOT_SCALE)
presentation2.slides[0].shapes.add_clone(map_chart)
