Voxal not working in Discord?

[Borbulous]

I installed Voxal in the hopes of using a voice changer on Discord, however in the input device drop-down box where there should apparently be a Voxal option, I only get a few mic options, with nothing to do with Voxal. I haven't tried much to fix it as I am unable to find anything related to it online and so am stuck for solutions, so I would really appreciate some help in figuring this out, thanks in advance.
