When I use <CornerstoneViewport />, I get ReferenceError: window is not defined.

And if i dynamically import, i get the following error...

Unhandled Runtime Error TypeError: Cannot set properties of undefined (setting 'cornerstone')

377 | console.log(cornerstone tools ---- , cornerstoneTools.external); 378 | // Cornerstone Tools

379 | cornerstoneTools.external.cornerstone = cornerstone; | ^ 380 | cornerstoneTools.external.Hammer = Hammer; 381 | cornerstoneTools.external.cornerstoneMath = cornerstoneMath; 382 | cornerstoneTools.init();
