I was not sure whether changes should be made to the controls.js and it's unit test file, so I ended up not changing them.
Will they need changes too? If yes, then how could it be done? 🤔

You can follow the guidance that @adamziel shared in #27094 (comment) for the file with controls - a separate file with constant for the store name.

This part is good to go, you can open a follow up with the remaining changes 😄

@gziolo Sorry for taking so long to reply, things are kinda crazy around here... 😅
I'll take the constants approach. Can I do it in this same branch or should I create a new one? Or it doesn't matter? 😸

[gziolo]

No worries, it's fine to have several smaller focused PRs. It doesn't matter which branch you use, it's probably easier to have a new one off the upstream master branch. Thank you again for your contributions 😃
