Multiple languages, emojis and input sources in virtual Accessibility Keyboard in MacOS

In MacOS's on-screen virtual keyboard for accessibility, I'd love to learn about the readiness of multi-language support. More specifically: 1. Languages other than English - is there some easy or built-in way to address the need for multi-lingual users? I can think about various possible solutions (and I'd love to both hear about other solutions and if mine are feasible/available), whether by - showing a "language switcher" button (to function the same as the regular globe key/button in physical keyboards of Mac/Apple) - automatic switching to the currently chosen language of the global input-source in the system (eg by using the language button/icon in the menu bar, and it's selection menu) - to show multiple virtual keyboards simultaneously (whether with separate windows, or showing 2 language panels in the same window). 2. Emojis - - Is it possible to show Emojis in the on-screen keyboard? I'd love to know if macOS supports some standard/builtin keyboard keys-layout for emojis (eg similar to the emoji keyboard in iPhone/iOS) - Also, is it possible to show some popular emojis, right within the main keyboard (just like showing numbers, alongside letters), instead of changing the input-source or keyboard layout to "Emojis" specifically? If nothing of the above is available, then - is the only way is to create custom panels by myself, or to use the dedicated Emoji/character-map popup tool (which is not part of the Accessibility Keyboard and works independently)?
