How to get a "link to this slide" for any slide of a PowerPoint presentation through Microsoft Graph API ?

Question

Context

In PowerPoint (Office 365), you can generate a shareable "link to this slide" for any specific slide of a presentation. When pasted in a new browser tab for example, this links re-opens the presentation at the exact same slide.

If unclear, I am referring to the feature described here: https://www.youtube.com/watch?v=XDtpmKxVLLY

My specific issue

I am trying to get (or generate) this link via Microsoft Graph API for a PowerPoint presentation that lives on a SharePoint site, and I have failed so far. I now wonder if this is actually supported by the Graph API.

What I have managed to do so far:

1. get a link to the presentation with

GET /sites/{site-id}/drive/items/{item-id}/webUrl

-> the drawback is it opens the presentation on the 1st slide each time, I didn't find any way to have the request generate a link for a specific slide.

2. similar with

POST /sites/{site-id}/drive/items/{item-id}/createLink
Request body {"page": "3"}

which generates a link to the presentation 1st slide, not the 3rd one (maybe I am using a wrong argument name ?)

3. generate a link to the preview of any specific slide with

POST /sites/{site-id}/drive/items/{item-id}/preview
Request body {"page": "3"}

-> the drawback is this is a link to a "preview" of the 3rd slide here, so it does not correspond to my need which is to open the specific slide in PowerPoint 365.

Question: Could you please confirm if what I am trying to achieve is supported by the Graph API or not ? If not, are you aware or can you think of a work-around ?
Thank you very much in advance.

Some additional details just in case

• My web app is accessing SharePoint site via app-only access.
• I do not have any trouble in authenticating into the SharePoint, accessing the presentation, downloading it etc. via GET/POST requests.
