❔ question: ‏ Are we creating this helper only for this purpose ? Seems a bit too much for me, can't we find a different way to share this code ?

[jonathanmos]

Potentially this class could hold additional common logic in the future, and I don't see a better place at the moment to put this. Let's discuss

[mariusc83]

I think instead of creating one class and one instance for this I would rather have this call duplicated in those classes. I am waiting to see what the others are saying also.
