How can I click/target at a pseudo element with Selenium IDE for Chrome?

I'm currently trying to click at a pseudo element of a search icon on a customers website. Sadly, I've found now way how to do this. I've started with trying to click the parent element with:

But this ends up in a timeout because the element can't be found (before element). The structure of the element is following:

<span id="et_search_icon">
    ::before
</span>

So is there any way to target the pseudo element within Selenium IDE for Chrome?
