Can't use hardhat plugin to generate gas metrics

Hi, I'm trying to use the package: hardhat-gas-reporter but I can't get it to work correctly. I've installed it using npm install hardhat-gas-reporter --save-dev but when I run my tests using this command no gas report is generated:

"testHardhat": " npx hardhat coverage --testfiles \"jestTests/tests/**/*.test.ts\"",

I've included the following import in my hardhat.config.js file

import "hardhat-gas-reporter"

The tests work correctly but no report is generated.

Have you tried without the coverage part ?

Yup, I've tried. Nothing changes. I must have something that it doesn't like in the configs

You are using Jest. hardhat-gas-reporter is for Mocha exclusively, at least according to the readme.
