Insert your browser log here, this could for example include:

Looking at the Javascript console, clicking on 'Add group' does not result in any console entries except another repetition of

'jQuery is deprecated: The global jQuery is deprecated. It will be removed in a later versions without another warning. Please ship your own.' for global.js

There is a JS error 'Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”).' on page load, but this was also present with the NC 21.0.2 instance where the 'Add group' still worked.
