Hi all, I've got a client wanting to do some A/B split testing on a site and I've setup a variation with some custom JS, but I'm not too sure how to load the url as the B variation to "manually" test whether the JS is working as expected. A basic example I've got just for simplicity is in my control there is no JS and in the variation I've added

alert('growthbook testing');

How can I load the url and see the alert consistently? I'm hoping there's some secret url param or something. Thanks for any help!
