Hello, i was having the same issue with a similar case.
I managed to find a solution that works for the desktop version, you can find the documentation here https://learn.microsoft.com/en-us/javascript/api/requirement-sets/word/word-api-desktop-1.2-requirement-set?view=common-js-preview (see Body.Shapes)
Using this you can retrieve all shapes including inline and floating images.
Hope this helps!
