An API for this is in our roadmap, but it's not currently available. It can be achieved by observing the changes to the console element where all the output is written. This was discussed here: https://discord.com/channels/988743885121548329/1103695759779573850/1197282830485569606

We use this technique for our JavaFiddle, and the source is available: https://github.com/leaningtech/javafiddle

Here's another example of a class that subclasses java.lang.Process and returns System.out as an input stream:
