Hi,

Thanks for the PR, everything seems ok, I don't have much to say.

However, there's one missing thing.

Since we include a CollectionDecorator, you need to add the new method in it as well.

Once that issue and the other minor inline comment are done, I'll wait 24h before merging it, so @AlexandruGG is able to review it as well.

Once again, thanks for taking the time to do that !

PS: Do not mind the static analysis issues with PSalm, we are working on it in #287

@ktrzos Are you at ease with the requested changes? Feel free to ask more info if needed!

@drupol

Sorry. Didn't have much time during the last days. But things are fixed now 🙂.

[drupol]

It's super fine, no worries.

Thanks for fixing it !

Thanks for the contribution! 👍

A couple of minor comments - I'll approve but please update the docs accordingly.
