Typescript RealtimeDragSelectingTool import issues

Question

I recently moved a project from JS to TS.

We used to use RealtimeDragSelectingTool as schema.toolManager.dragSelectingTool by importing gojs/extensions/RealtimeDragSelectingTool.

I saw that there is two import methods while working on typescript by using extensionsJSM or extensionsTS.

First I imported extensionsTS but got the same error as this stack overflow question, who in fact did not have a clear answer.

So I imported extensionsJSM, it is working but I have that error comming up in my IDE

Simply copy the extension file to your project and import it, it works fine RTFM...
