Call Take Recorder Function Library from Blueprint

I would like to call the functions in the Take Recorder Function Library out of my own project Blueprint Function Library.
The C++ Class UTakeRecorderBlueprintLibrary contains BlueprintCallable Functions but they do not appear in my Blueprint (even with Context off mode).
The Take Recorder plugin is actived. Do I have to add any dependency somwhere else?

It must be somehow possible since VirtualCamera Function Library calls theses functions in their Blueprints.
Thanks for any advice.

Update: Since 4.26, Take Recorder functions are only callable in Editor Utility Blueprints:
