How can I correct a spelling error in my domain name?

I've made the mistake of a spelling mistake in when setting up my shopify account. The domain name is correct.

i used the word "N" in stead of "B" so it says hernal instead of herbal, is there any way to fix this issue. Here is what it looks like shopify.com/store/hernalstems its meant to say herbalstems. Any feedback would be much appreciated.
