Slightly customized us and ru layouts for squeekboard for use with Poco X3 Pro (vayu) on 300% scaling. Also added the little hack so the russian layout would mostly work correctly in all apps.
It's a little wider than original, so it extends to the edges of the screen and also have comma key on the default view, so you don't need to switch to numbers to type it.
Put the yaml file into ~/.local/share/squeekboard/keyboards and it will work immediately
