'How to run Jest tests with coverage for one file

I want to have coverage report for only one file that I am working on at the moment.

It is a bit overwhelming to have the full table of coverage for the whole application files and then search for the one I need.

What I tried was to run test for one file and add --coverage. But it shows coverage for all files:

package.json

...
"test": "react-scripts test",
...

My command

npm test my-component.test --coverage

Is there an option that I can add to this command to show me only my-component.tsx coverage?
