@ludovicobesana as you recently updated the Italian translation and if you're ok with it, can you adjust it as well to factor in the changes? It's mostly a minor change to the screen section.

Let me know and we'll take it from there.

Hi @jonniebigodes ,
Of course! I'm available. 🚀

Could you kindly provide further details or specific instructions regarding
what needs to be changed, and I will proceed with the corrections.

I look forward to hearing from you with additional information.
In the meantime, I'd like to take this opportunity to wish
you a happy holiday season. 🎄

Thank you!

@ludovicobesana, thanks for following up with me on the changes. Appreciate it 🙏 !

And it's just a couple of minor changes on the Screen page:

• In the "Mocking API Services" section, update the snippet to use mswLoader instead mswDecorator, and adjust the preview configuration object to factor in these changes as demonstrated here
• A bit down on that same page, in the "Write an interaction test using the play function", replace the Storybook package import for the testing from @storybook/testing-library to @storybook/test and add the aside below the snippet with the equivalent as written in the section here

Let me know if you have any questions and we'll take it from there.

Thank you so much for the wishes, and to you as well @ludovicobesana. Hope you and your family have a fantastic holiday season as well. 🎄 🎁
