Better PHPUnit extension won't run (VSC)

I installed PHPUnit with composer and started to make a quick test just for fun.

When I run the test with php vendor/bin/phpunit tests/PrimeFactorsTest.php

The test runs and shows output on vsc terminal.

The catch is that I installed a vsc extension called Better PHPUnit by Caleb Porcio to improve the experience of testing and having better colored outputs. Yet, when I run the method or file with cmd + shift + p as the extensions docs says, nothing happens. Not even an error message.

Anyone knows what it is wrong?
