Adding An Emoji Picker

We can use the willRenderShapePresetToolbar hook to add custom shape preset tools to the sticker and preset toolbars.

In the example below we use emoji-picker-element to add an Emoji picker to the preset tab of the annotation util. We can see an example of this control on Edit • Photo
