This describes the error and we have the option to navigate to the failing cell. If we click it we get:

As you can se it marks the cell with red border and its number colouring is changed.
The idea of this Spike is to investigate whether we can show the message on the notebook as well for example like this:

If possible also adding new style to the output should be consider to show that this is a different output than the standard Jupyter one.
