Content Lock Pro - CSS Selector Triggers?

Anyone using Content Lock Pro and familiar with how to use the CSS Selector Triggers? I am trying to have my Content locker pop up when someone clicks a link on my site. I read the tutorial but did not find much information on how to set this up.

Anyone know how to set up CSS Selector Triggers for links, What should be put in your website's html and what within the CLP site?

I am trying to use .my-link-class but am stuck after this.

send a support to CLP,i think they can help u
