Getting information about a suggestion from a suggestion ID in Google Docs API

I'm currently using the documents.get API method to retrieve documents with suggestions inline, returned as so:

{
   "startIndex": 108,
   "endIndex": 159,
   "textRun": {
     "content": "This is some content that I have suggested to insert",
     "suggestedInsertionIds": [
        "suggest.fakesuggestionId123"
     ],
     "textStyle": {}
    }
}

I would like to retrieve information about this suggestion (i.e. who wrote it and when), but I can't see any endpoints in which the suggestedInsertionId values can be queried. Is there a way to retrieve this information in either the Drive or Docs APIs (outside of exporting to docx)?

Solution

Currently this information is not available via API

It is available for comments via Comments:get, but not for suggestions. There is a related feature request for it on Public Issue Tracker.

You can "star" it or comment on it to increase visibility.
