Skip the "Hello there" Onboarding screen/pop-up in the Dev Client

Hello there!

I’m attempting to disable the onboarding screen in the Dev Client but am having no luck. I’ve appended disableOnboarding=1 to the URL, as the docs say, but this still shows the screen.

I got this from here: Running E2E tests on EAS Build - Expo Documentation

I’ve also tried other methods such as setting launch arguments when starting the app itself, but that doesn’t seem to have worked either.
This is what else I’ve tried: Prevent initial "Hello there" popup - #3 by notbrent

The URL I’m using when launching through the dev client is:

(I’ve edited out private info and replaced things with myapp because it’s a clients app)

I’m struggling to find out what’s going wrong. Thanks for any help.
