Indenting OCaml code in visual studio code

Question

There are several questions here on indenting code in visual studio code (How do you format code in Visual Studio Code (VSCode)?), and on indenting OCaml code (How to indent existing OCaml code), but none of the answers work for indenting OCaml code in visual studio code. I have installed the OCaml Platform visual studio code extension, vscode-ocaml-format (following https://dev.realworldocaml.org/install.html), ocaml-lsp-server (following https://ocaml.org/learn/tutorials/up_and_running.html) using opam, updated and upgraded everything, used eval $(opam env), but this still does not work. I'm a bit at a loss...
