Open a specific Squarespace social link in same tab

Site URL: https://www.angeliquemartina.com/home

Hi, I've created a custom social link (a search icon) to appear in a Squarespace 7.1 site header. But these social links are set to automatically open in a new tab. I would like the Search ico n (only this one) to open in the same tab. 

Hope there is someone out there with the solution! 

So far, this is what I've come up with. But it targets all social links (not only the search icon link) 

<script>

$(function(){ $('[target]').attr('target', '_self'); });

</script>
