How to configure the Racket interpreter to support command history?

Question

I just installed Racket and tried the interpreter.

However, I apparently cannot go up and down the command history using the arrows (or Ctrl p/ Ctrl n) or use Ctrl rto search through it.

Is it supported? Can I create it using this function?

Based on the Python background, I’m very used to these features and would like them to be available for Racket too.
