You have the oldest release of the library possible 😅. If you installed that version on purpose, you can find its usage in the README of https://github.com/kreait/firebase-tokens-php/tree/1.0.0

Otherwise, check the composer.json file in your project and require a newer version, e.g. ^1.15 to make sure that you receive future updates of the 1.x branch as well. 🤞
