import { Keyboard } from "https://dotland.deno.dev/x/grammy@v1.22.4/mod.ts";
Make the current keyboard selective. See https://grammy.dev/plugins/keyboard.html#selectively-send-custom-keyboards for more details.
Keyboards are non-selective by default, use this function to enable it
(without any parameters or pass true). Pass false to force the
keyboard to be non-selective.
