@pensarajustica If I were you I would create another web site, say a microsite, which is just one html page that uses Zoom Web SDK and lets your users join a meeting. This may require a pro account or developer account, I don’t know much about Zoom account tiers.
I recommend cloning Zoom Web SDK Sample App You can just use the example in the CDN directory of the sample app. The next step is hosting that single page. The easiest hosting method for your case is, imho, a static web hosting. There are many hosting providers that support static web sites such as Firebase, Netlify, and Vercel to name a few.
Once you deploy your site point your iframe to it by setting src=“YOUR_ZOOM_WEB_SDK_MICRO_SITE_URL”. Don’t forget to set the allow attribute on the iframe to let fullscreen and microphone.
That means you’ll have 2 web sites, the one you built with wix and the one that uses Zoom Web SDK.
