Can't find Associate Tag, API and Secret Key

I had uploaded and installed WP Amazon Plugin.
I activated the Plugin in my Dashboard http://www.sacristies-of-the-world.com
I was trying to following these instructions below:-

“Activate your Plugin in your Dashboard and go to “WP Amazon > Settings > Amazon”. Enter your Associate Tag, your API Key and your Secret Key and choose the Amazon Shop where you are registered as Affiliate. Where do you find the Associate Tag. For this, you have to log into your Affiliate Account. In the left sidebar you find your Tracking ID. To find your API and Secret Key – which WP Amazon needs to log into the Amazon API – go to Product Advertising API > Manage Your Account > Access Identifiers. After you saved this data, the WP Amazon Plugin is ready to run.”

I logged in to my Affiliate Account to find my API and Secret Key, gone to Product Advertising API, Manage Your Account, and clicked on Access Identifiers. It asked me to sign in to my Amazon account which I have done. This is the page I am now on:-
https://portal.aws.amazon.com/gp/aws/securityCredentials

I can’t find the Associate Tag, API and Secret Key. Can you help? Thanks.
