Show message text in scene view

Hi! So I want to show a message notification/pop-up like the one you get in the Game View in play mode when trying to save the scene, example in the image:

But I want to show it not in the game view, but in the scene view. And this during editor mode, not play mode. Is this possible?

Old, but I was with the same issue and this is working for me (I realise some delay after call the function, maybe because of “foreach”).

foreach (SceneView scene in SceneView.sceneViews)
scene.ShowNotification(new GUIContent(“Your message here.”));
