Cannot add flags after the script

I am executing c8 like so;

c8 --src=src/ npm run test

Where npm run test is a custom defined npm command with its own parameters.

Sometimes I need to generate a report, so I do

c8 --src=src/ --reports-dir=coverage/ --reporter=text --reporter=lcov npm run test

All good.

Looking at help, it appears that c8 allows additional parameters after the script

$ npx c8 --help
c8 [opts] [script] [opts]

I tried to execute flags like so, but the flags after the npm run test script are ignored

c8 --src=src/ npm run test --reports-dir=coverage/ --reporter=text --reporter=lcov

How can I add the flags after the npm run test script?
