While it technically works, it's rather unsuitable to access the emoji keyboard from somewhere else to add recent emojis.
Recent emojis being stored in the keyboard very much implies that this is meant for emoji keyboard use. When you want to to extend it for use it from normal input, emojis should be stored in a neutral place.
