Current Behavior

When sending an Javascript nested array such as:
const groups: any[] = [];
groups.push(['a', 'b', 'c']);
groups.push([1, 2, 3]);

If I push an object with this shape over the bridge, I get an error from the bridge before it calls the plugin method:
JSONArray is not a valid type. Valid types are simple types and dictionaries and one-dimensional arrays of those types, including MutableDictionary, Dictionary, Map, MutableArray, Array, List, Blob, Date, String, Number, Boolean and null

This same object works just fine on iOS. On iOS I'm using Swift and on Android I'm using Kotlin.

Expected Behavior

I would expect that the nested array would serialize down to a JSONArray and be usable in my plugin. I've looked at passing over the information as a string and then serializing it and deserializing in Kotlin but this is a massive hit in performance when sending large JSON objects (our max is 20 MB in size) per object.
