Blocking obtrusive emojs

Desktop Telegram is a wonderful communication medium with a couple of drawbacks : 1. The creators of it do not answer the questions that they enable being asked, and 2. The window with Emojs, Stickers and Gifs infuriatingly keeps covering over the chat window - it has to be constantly cancelled to continue chat. It is because of the first drawback that I am here posing my question about the second. I don't use, want or need emojs etc, so my experience of Telegram would be greatly enhanced, if the 'popping up' of that window could be prevented - as distinct from remedied. Any ideas ?
