Big button to stop a tutorial?

[Nics-Github]

I know there is the little stop sign, to terminate a learnr tutorial in the IDE.

Because we are running on a Rstudio workbench server with limited resources, I'd like to help remind my students to terminate their tutorial instance. Is there a way to stop a learnr tutorial from within the tutorial itself? Like a button to terminate it on the last page of the tutorial.
