WebSocketConnect Plugin not installed (no files) but Katalon says it is

So I tried to download and install this plugin. However, it does not appear to have ‘downloaded’ ? Katalon says it is installed, but I do not see anything in my Plugins folder or any ‘CustomKewords’ files as the sample test shows.

Any help would be great. thanks

there is any particular reason to open two discussions on this forum, with same content?
please decide which one do you track and discard the other one
