[image-tool] Close Button Not Working in View Mode

[seungdeok]

Describe the bug When in view mode, clicking the close button doesn't perform the expected action. The issue appears to be related to function handling in the view.ts file.

To Reproduce Steps to reproduce the behavior:

1. Open any data in view mode(image-tool)
2. Try to close it using the close button
3. Notice that the close action doesn't complete properly(ex. close the browser tab when clicked)

Expected behavior The close button should properly close the browser tab when clicked.

view.ts

AS-IS

function onAction() {}

TO-BE

function onAction(action: FlowAction) {
  switch (action) {
    case FlowAction.close:
      onClose();
      break;
  }
}
