How to chosing the "model" when adding a slide in a presentation ?

Hi SF & users,

note: I am unsure of "model" naming (it may be "Template page", or "theme" or "mask" in the pptx world ... I don't know) so I will describe how I do it in MS PP:
In MS Powerpoinbt, when I click the "add slide" in the ribbon, I have several models(?) poping up below as icons & I chose the one I want from my existing Template. This is the feature I want to reproduce programmatically when using the SF lib after loading that presentation used as a Template.

So when I use .add(...) to add a new ISlide i see several options, but all leading to load only one same "model" from the ones I see in MS Powerpoint
I guess there is a <list> of these models in the original .pptx.  --> So how can I access these "models", either by their index or by their name ? (any way would be OK for me as I can see/know their name in advance)

Likely one of the options of .'add(..)' but I don't see it ...

Thanks in advance,

Hi Arun,

Thanks for the effort, but that is not exactly my question
Of course I can add one slide of type SlideLayoutType.Blank, SlideLayoutType.Comparison, SlideLayoutType.ContentWithCaption, SlideLayoutType.PictureWithCaption, SlideLayoutType.SectionHeader, SlideLayoutType.Title, SlideLayoutType.TitleAndContent, SlideLayoutType.TitleAndVerticalText, SlideLayoutType.TitleOnly, SlideLayoutType.TwoContent, SlideLayoutType.VerticalTitleAndText
but that is not the need.

I need to add a slide from a "model" that is in a presentation opened as a Template. Not copy an already existing slide, but one that is proposed by MS PowerPoint when you click "new slide". These are not necessary the SlideLayoutType from above -sorry again, likely using "model" in this thread is wrong-

In can not attached in this forum a pptx as example, but please see incident ID: 157742 (about a bug): I have attached a Template there for other SF purposes. Please opened it and try to programmatically create a slide from the last choice proposed when you click "add new slide" inside MS PowerPoint.
This pptx belongs to a customer - Please do NOT put a public example that includes that Template nor a screen capture of it
Please just explain or write the minimal code how you access that slide model in presentation.Slides.Add ???) for a new slide
