How to pass an unsigned int 64bits to ak.soundengine.getSwitch from Reaper LUA

Question

Hi, so we can now leverage ReaWwise from Reaper to send WAAPI queries to Wwise from Reaper, as shown in this blog post: https://www.audiokinetic.com/en/blog/waapi-in-reascript-lua-with-reawwise/ It's great to have access to this, but I'm hitting a wall: I want to query wwise for a switch value on the transport game object, so I need to pass an unsigned integer 64-bit along with an ak.soundengine.getSwitch query. How do I package that number? I tried reaper.AK_AkVariant_Int(), but the ID is too big. I also tried AK_AkVariant_Double, AK_AkVariant_String, none seem to please WAAPI. Any details on the AK_AkVariant_XXX methods would be great :)
