How to make textbox edge transparent in figure?

I create a text box in a figure by clicking Insert -> Text Box, then I try to change the edge color by right clicking the text box and clicking Edge Color, but I do not see an option for making the edge transparent. Is there a way to make the text box edge transparent?
