@francisbesset thanks for this. However ... this is a bit tricky. The config example is only an optional config option ("if you want, use a custom method name") so it's not directly related to the example above. But I can see why that can be confusing. Let me think of an alternative solution for this.

Thank you for your answer.

I understand, however the PHP code and the configuration are in same chapter section.
If I copy paste two parts, the method name mismatch.

I trust you to find the best solution. 🙏

At the end I commented the optional options: 3d04404 and made more clear the distinction between the mandatory options and the optional ones.
