Thank you for the review :)
Unfortunately, I do not have the required environment to test Geyser support, so it just can't be implemented well enough.
There's an issue related to Geyser UUID support on GitHub, you can check the technical details on it there:
https://github.com/voidpointer0x00/VoidWhitelist/issues/9
If, luckily, you have time to test builds that I'll post there, please, respond on GitHub that can do so and I'll start working on it :)
