"Command failed: tox -a 'tox' is not recognized as an internal or external command, operable program or batch file." error when attempting to run any tox commands

when pressing F1 and run "Select and run tox environment", the following error appears:

this may be caused by the fact that tox is installed inside my pdm project's venv, not globally. if that's the case, it should use vscode's python interpreter path to locate the tox executable. this is how most other extensions work

I believe it should also be able to run test from an arbitray path (even outside the interpreter).
Many tools support both. For instance black defines the black-formatter.path and black-formatter.interpreter options.
