Itamp;#39;s loading, okay great, so here is the DMN editor in an empty state. You can already already add nodes here. It will work perfectly. If you, if you needed just a viewer to your diagram you could add the diagram content here and change to read only true, then the the diagram would be static and this will be it, but in this case this example is about doing, uh, an editor so we need to implement those those buttons, uh, actions. Okay? So letamp;#39;s do that now. For instance, letamp;#39;s start with the undo button. Copy that, undo. Letamp;#39;s add an event listener for the click event. With the function. Okay, so when the user clicks undo, we need to call the undo method from the editor. So, simple as that. And letamp;#39;s do this same thing for the redo button. Okay, so we have an event listener for the click event and we are calling the func so letamp;#39;s check if this is already working. Okay, so letamp;#39;s add some nodes. And try to undo.
