How to compare Json with different case in property name?

Hi, 

Is it possible to compare properties ignoring casesensivity?
Example:
``` 
var actual = JToken.Parse(@"{ ""KEY1"" : ""value"" }"); // uppercase property
var expected = JToken.Parse(@"{ ""key1"" : ""value"" }"); // lowercase property
actual.Should().BeEquivalentTo(expected);
```
I couldn't find any info about this. Also chat is inaccessible for me.
