ResourceDictionary as NuGet Package

I'm currently trying to create sort of a XAML "Style collection" which we can use in all of our UI projects, to achieve consistency in our visuals.

I've tried creating a class library and added a ResourceDictionary with my style:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"><Style x:Key="ToggleSwitch" TargetType="{x:Type CheckBox}">        Some style in here</Style></ResourceDictionary>

Enabled building the NuGet Package in the build options and added it to another UI project.I just can't quite get my head around about how to actually use the style in the UI project now.

Is this even a valid approach?Googling this specific intend didn't get me any reasonable results.
