doom-emacs *utop* buffer

[idurand]

I recently switched to doom-emacs because utop/ocaml became too complicated to configure.
In classibal Emacs, the utop buffer was in an Emacs window easily accessible with C-x o (other-window).
In doom-emacs, the utop buffer seems to be just a buffer; it can be reached from a .ml file with C-c-C-z (switch-to-repl)
but not manageable as a window.
How can I have the utop buffer inside am emacs window accessible with C-x o.
