code before the </body> tag

Hi,
I need to insert a small JavaScript Snippet before the tag of all the poage of my site.
I don’t know exactly where to place this code.
Can anyone tell me how to do that?
Is it on the “site code” area at the bottom of the editor?

Thanks for your help.

You would do this on a premium site (only) from your Wix Dashboard via your Tracking Tools & Analytics section. This is where you add custom code: https://support.wix.com/en/article/about-tracking-tools-analytics
