@Nullable fun getPersonalStickers(): java.lang.Boolean
If enabled the user can create personal stickers from the device's photo library. A
button is added as first item
in the menu in front of the sticker categories which modally presents an image selection
dialog for personal sticker creation.
Personal stickers will be added to a personal sticker category with the identifier
"imgly_sticker_category_personal"
which
will be added between the button and the regular sticker categories if it does not exist.
