How to quickly add float window to tab via drag&drop?

Hi, is it possible to quickly add float windows to tabs in the editor via drag&drop? I feel that it is set up there, it just doesn’t work for some reason.

What platform do you use? On macOS it’s missing some functionality that we want to implement.

Windows 10, I use the master-branch version from 09/19/2023.

I have already figured out how to do it. It works, but it wasn’t immediately clear to me that the float window needs to be dragged into the blue square. Please, could you add this to the documentation?
