Can't insert citation

I have Mathematica 13.1, and EndNote 20 installed on Windows 11.
According to the documentation, if EndNote is running, I should be able to insert bibliographic references into the text cells of the notebook.
However, when I select sequentially

Insert → Citation → Bibliographical Note

What appears is a blank window screen.

Is there a solution to this problem?

HI Tsai,
I used EndNote 4.0.2 and Mathematica 9 or 10. I don’t recall exactly. It worked great. I found that citation would use a new reference number for reused citations and would not build the Bibliography correctly after using an updated version of Mathematica. With Mathematica 13.0.1, EndNote 4 no long responds properly. I use Zotero now and created a bibtex file. Mathematica 10-13 just gives an error message when reading my bibtex file. I think it get errors when tittles use LaTeX equations. I haven’t been able to track it down even with the help of text support. It’s disappointing since it a very useful function when it works.
