Great icons!
I took the liberty of making a version Fluent UI which works with both light and dark modes, since we didn't have any examples of how to do that yet.
It turned out it required some changes on our side, which are in the beta we just put out.
It's up to you if you want to change the original/definitive set to work the same way. It does make startup a bit slower, as there are more icons to load, but only a fraction of a second.
