We have a 200 page WIX website in Spanish and English. I would like to talk with someone who has professional experience on multilingual websites with WIX. Thank you!
https://support.wix.com/en/article/creating-a-multilingual-site-663444 seems to answer your question.
And best talk with someone about your entire project.
WIX can have serious limitations, depending on where you plan on taking your site in the future.
Best to first ensure WIX is your best solution, throughout your project's entire life cycle.
