Katalon V7: How to rename a file on the Desktop

Hi All,
So I have what I would think is a simple issue.

I thought I could do this with Katalon V7, but it seems like there is just Desktop application control, but no ability to manipulate the Desktop itself.

What I am trying to accomplish is the download a file from a website, then rename it.

I can get the downloads to work, however when getting tot he desktop portion I do not see how I can rename the file.

Can anyone point me in the right direction to make this work?

I have the same question.
Did any body have the solution
