For Unity projects, NuGet installation packages cannot be used

I use NuGet to add the packages I want to use in my Unity project, but it doesn't work in Unity; I can't use the newly added packages. Can you add a feature that allows using NuGet to download packages directly in Rider and apply them to Unity projects (I know there is a Unity plugin called NuGetForUnity that has similar functionality, but I don't want to add more plugins to my project)?
