Adding global site tag

I know wordpress well but am fairly new to seo and yoast. A client asked me to add a Conversion Tracking Tag aka Global Site Tag aka gtag.js to the site. Before doing so, I wanted to figure out the best way. Is there a place in Yoast SEO to add the tag? I searched and couldnt find one but wanted to check.

If there is no way in Yoast to do so, what would be the best way in WordPress to add the tag? Thank you for any info.
