Hello, I'm having a hard time with the language selector. I did all the steps from here: (https://www.multilingualizer.com/support/language-selector-configuration-and-customisation) In Wix go to Manage Website -> Tracking and Analytics -> Add New Tool -> Custom and fill the box in as pictured. and it still didn't appear in the header.. I'm not sure what I'm doing wrong. should the site be published first? or should I add anything else to the code? Please help!
