Read Text from Clipboard

I am trying to read the text in the clipboard in C# in Unity and then set it to a variable.

I have seen this article however it doesn't seem to work in Unity: https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.clipboard.gettext

I just want to be able to read plain text. No images or anything. I have also found a few other articles on this however none of the code works in Unity.
