FlickType on the Apple Watch?

Hello, everyone.
I have just become the owner of an Apple Watch, and was going through setup when I remembered that, though their phone component was discontinued, FlickType had a watch keyboard offering. I also remembered hearing that this, like their previously mentioned phone application, was accessible, so I went to install it. But now, I'm having an interesting hurdle: I load the app just fine, the keyboard presents, and I'm told that I need to activate direct touch via the rotor. This is well and good. I'm very used to doing this on iOS and I'm more than happy to comply... except that its not anywhere to be found on the rotor. I've since combed through the settings on both phone and watch and see no way to modify the rotor options, and with Google unable to give me answers I'd figure I'd post here. Is the app unworkable after all? And if not, what am I doing wrong? Any tips would be greatly appreciated.
Thank you so much in advance, and I hope everyone's days are filled with peace.
