Since your toilet is set into the wall, you'll want to tap into the faucet line instead. Simply get a splitter and add the washlet hose there. The washlet will replace the toilet seat on the toilet.

Where it is best to attach the splitter?

If you shut off the stop to the sink you can unhook the supply line and attach here

However this is not the same size threading as a toilet valve so any included adapter will not work, a trip to the hardware store should get you sorted.

Bring the included adapter and this picture

It would go directly on the cold water shut off valve. It'll then have an identical connection at the top to reattach the faucet cold water line (looks like a 1/2" compression). Lastly, it'll have a connection on the side where you can attach the washlet hose. Until you select the washlet, you won't know what size/type that connection is. So you should get the washlet first, and then get a splitter that is 1/2" compression inlet, 1/2" compression outlet 1, and then whatever the washlet needs for outlet 2.
