Answer 2: Yes, I did a whitelisting PR for my first collection. The PR included a few files that needed to be whitelisted in order to ensure that the collection was properly protected against malicious actors. I also included some additional information in the PR, such as a brief description of the collection and a list of the items that were being whitelisted. After submitting the PR, I received feedback from the Kukai team and made the necessary changes to ensure that the collection was secure. Finally, the PR was accepted and my collection was successfully whitelisted.
