Generate all missing mli file

[qazxcdswe123]

Hi

This might be off topic and feel free to close it.
I have a codebase with 200+ ml file without mli file, and the extension can correctly generate mli file by clicking the switch implementation/interface button top right.
Is there a method to generate all missing mli file/programmatically generate mli file, without clicking the button one by one?

I've tried using bash script with ocamlc -i matched.ml and dune exec -- ocaml-print-intf matched.ml, no luck. This extension is the only working way to generate mli.

Thanks
