[LucasChenZQ]

The codes are directly copied from README.md's Usage section, and cause AttributeError in the first code. it seems that the helper module is trying to access a variable from emoji package that doesn't exist

Enviromnents:
macOS - 14.1.1
Python - 3.11.6
pilmoji - 2.0.4
emoji - 2.12.1

The error are as follows:
