Couldn't detect installed module paths?

[anta40]

I'm on macOS 15.2 (M2) with OCaml 5.2 installed (via opam, not homebrew). I also have various tools like ocamlformat, ocaml-lsp-server installed.

Seems like vscode-ocaml-platform (mine is 1.29.0, and yes it properly detects my opam switch:5.2.0-flambda) ) couldn't detect installed module path (lwt, cohttp etc are also installed with opam):

Seeing those red underlined texts are a bit annoying.

No issue compiling the code, though, like this:

ocamlfind ocamlopt -o redditdemo \ 
   -linkpkg \ 
   -package lwt,cohttp,cohttp-lwt-unix \
   -thread 
    reddit.ml

Wonder if I didn't configure vscode-ocaml-platform properly.
