Hi @ErenHatchet,
What I would suggest you do, when you create each of the widgets, take the output and assign that to a variable like you have done with the Pano which you are setting to the base UI. Then when you want to remove that specific widget, you get that variable, I.E, Base UI and put that into the input for the Remove from Parent node.
Get Base Ui → into Target of Remove from Parent
So something like this:
“I should step on a cube and a button that says “click here to read” should appear, which it does” → Add this Widget to a variable. (ClickToReadWidget)
“On button click, the browser should come up, which it does at this point too” Add this widget to a variable
“When I’m done, I click the exit button and it closes the web browser widget, this also works” → Get ClickToReadWidget → plug into Remove from Parent node.
