About the paraview-medical

Hi!
I have a question about the paraview-medical. I opened the website https://paraview-medical.netlify.app/ and import my dicom series. But when I want to use the Paint or Ruler, I feel confused. In more detail, even though I clicked Paint/Ruler, I still can only use left mouse button to change the window/level. From the console, I get vtkProxyManager did not request an animation. So how can I do some annotations and measurements with the Paint and Ruler?
Thanks in advance.

Thanks for the bug report. I’m currently fixing the widgets in their entirety on the issue tracker. See: Issue #24 and PR #28.
