Hi guys!

I'm trying to make Lightning Experience Specialist - superbadge. And I'm stuck in step 8.

At the moment I need two helpers, the first one is: How do I post to the developer forum? I don't know if it's because I'm nervous, but I didn't find the option to post.

Regarding the step I tried to follow this topic but I was unsuccessful and am having difficulty deleting the data, if anyone can help me I would be very grateful.: https://developer.salesforce.com/forums/?id=9060G000000XbPEQA0
