Custom widget installation for Wix will not work because Wix only allows embedding third-party widget into iframe. OnVoard widgets needs to be executed within the same DOM as your main site so embedding into iframe won't work.
For most widgets, like reviews widget, you will be provided with Auto and Selector placement option, both of which should be sufficient to help you install widget to your site.
