Changing Domain/Website Name

I have recently changed my website name and have changed this to reflect in my CleanTalk dashboard, but is there anything else I need to do in my dashboard to make sure this is a smooth transition? I also can’t find the CleanTalk plugin to upload to my new website…sorry, I have had zero sleep so my brain can barely function right now and it’s probably right in front of me, but I’m not seeing it. Do I need to change the access key number, or maybe the better question is, should I change my access key number since I changed the website domain?

Thank you for any help,
