There are probably some games that this would work well for, but I'm not sure that it'd be a great replacement the way a physical thumb keyboard is for texting or the like.
Most present-day games that I can think of that I play use the keyboard as a grid of buttons. They expect to have your hand over the thing -- often the left hand, with the right on the mouse -- to let you be able to push multiple buttons quickly.
I'm not usually doing much text entry, which is what I'd expect a thumb keyboard to work well with.
Speaking of ties, I notice that Pezeshkian, unlike Putin, isn't wearing a tie.
And thinking back, I don't recall Ahmadinejad -- notable for his signature jacket -- wearing a tie either.
And looking at some presidential pictures, I don't see images of ties either:

Ah. It's a political thing.
