Smart Content API integration

Hi, I am trying to integrate with Smart Content API, then I am getting all the details which I have to copy to my AEM Smart Tag service in my local instance but then "Retrieve Client Secret" is not working for me I have clicked on it and it says "I don't have the access to edit". So, can you please help me as I have to paste this in my local configurations.

Also, I checked/validated the integration by going to Web Console > Main > JMX then searched for "Similarity search" and here in this, I checked on validate then getting the below popup.
