Hello,
I’m trying to create a plugin that works with Presentation files.
I have a question.
How can I get the user-selected objects?
For example, here is a VBA code:
I haven’t found any such event or method so far.
Is it possible to get them via callCommand API?
Hello, @KenjiOtsuka 
Unfortunately, there is no such method available.
We will consider your suggestion and try to add the method you described in future releases.
Hello @KenjiOtsuka,
I apologize for the delayed response.
We have submitted a proposal to implement a method for returning the objects selected by the user on a slide.
Unfortunately, we don’t have an exact timeline for this yet, but we will notify you as soon as it is implemented.
