[BUG] setUpDocHeader example documentation outdated

[calien666]

Current behavior

Acutally, the best practice on Creating a backend module shows the setUpDocHeader method with $moduleTemplate as param.
https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ExtensionArchitecture/HowTo/BackendModule/CreateModule.html#main-entry-point

Below the example method has 2 disadvantages:

1. the method name isn't the same as in the main entry point documented
2. the praram is not the same as expected
   https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ExtensionArchitecture/HowTo/BackendModule/CreateModule.html#the-docheader

Expected behavior/output

A correct example, how to use setUpDocHeader with the $moduleTemplate.

TYPO3 versions

12 (and possibly main)

Possible Solution

I don't know, what is best practice there.
