Hi @atzzCokeK 👋
I see that all you currently opened PRs are in draft. I assumed you did this to make us focus on one PR at the time, so we do not "bounce" between PRs and run into problems with the snapshot in an uncoordinated manner.
If that is the case, do we want to continue with this PR? Just mark your PR "Ready for review" if you approve with this process. The snapshot tests need an update and the locale file generation needs to be run again, as well.
We appreciate your support 🙏

@xDivisionByZerox Yes, what you mentioned is perfectly right. I’ll do a final check on this PR and mark it as Ready for review soon. Thanks you🙏🏽
