Unable to figure out the error from trailblazer

Question

Friends,

I am trying to complete my "javascript developer 1 certification maintenance summer 22" hands-on requirement. I think I have done as requested in the task below :

Get Hands-On with New Alert, Confirm, and Prompt modules and components. Create a new Lightning Web component Name: recordCardQuickFiles Import LightningConfirm from "lightning/confirm" Replace the confirm method with the LightningConfirm method Message: "Are you sure you want to delete all files?" Variant: "headerless" Label: "Are you sure you want to delete all files?"

However, when I try to validate the challenge, I'm hit with the error "Please make sure the prework is configured in the playground." . I have checked at length on what is the prework required, but no answers found. I posted the same query on trailhead community as well, still no luck (got some weird advices like enable/disable permission set groups in User management setting) . Any help would be greatly appreciated. Thanks

Struggled a bit but then I found the solution here:

https://stackoverflow.com/questions/73658945/problem-with-trailhead-get-hands-on-with-new-alert-confirm-and-prompt-modules

It seems as though the messaging etc. is very specific:

        const confirmation = LightningConfirm.open({
            Message: 'Are you sure you want to delete all files?',
            Variant: 'headerless',
            Label: 'Are you sure you want to delete all files?'
        });
