 To reduce magic to a minimum, no official API client is used: it's only just post requests and Server-Sent Events handling. The program only depends on [requests](https://requests.readthedocs.io/en/latest/), [sseclient-py](https://github.com/mpetazzoni/sseclient) and [CustomTkinter](https://github.com/TomSchimansky/CustomTkinter).
