After having a read through the documentation for [Get Library Matches](https://developer.plex.tv/pms/#tag/Library/operation/libraryGetMatches) I noticed there was a field where we can supply a GUID. In the description for the method, it states we should be able to use other GUID’s such as IMDb to help with the matching, but if I supply an IMDb id, no results are returned, and if I add a title to the query all I get is whatever the title matched, even if the IMDb id is for an entirely different movie/tv show.

I’m not sure if it’s implemented yet, or I’m using it wrong but would be awesome if we could match an IMDb id directly rather than relying on a fuzzy search that may or may not return what I’m after, even if there was a way to convert IMDb Id’s into a Plex Id which we could then use would be great.

Currently i’m attempting to call it as such `http://ip:port/library/matches?X-Plex-Token=token&type=1&guid=tt5052448` I’ve also tried using the guid format as `imdb://movie/tt5052448` and `imdb://tt5052448` but to no avail.
