White menu bar icon for dark mode?

This looks like it could be a very useful utility, but I use dark mode and I can find no way to switch the menubar icon to white. Even a short bit of documentation on the website would be helpful instead of a bunch of quotes raving about the product. I don’t care what others think at this point, I PURCHASED THE APP. What I want to know is the most effective ways to USE it. Emails to customer support have never been returned. Completely non-responsive.
