Library on word does not load


I am new with ENDNOTE. I use the free option myendnoteweb.

I downloaded and installed the word (version 16.46) EndNote PlugIn for my mac OS.

In the EndNote PlugIn preferences application, I set up EndNote online and it works fine.

On MyEndNote Web, I have a group with 91 references.

But, in my word file, when I try to INSERT CITATION from EndNote PlugIn, the window appears with no Library and no references (see image attached).

What I can do to solve this?
