How do I enable HTTP api in embedded node in 20.6?

Trying to update some integrationtests that use es 4.x. However, I can’t get the embedded node in version 20.10 to respond on http. (need to set up users etc as part of the test suite).

Is this not working or is there a setting I’m missing?

(es denies connections on http port completely, so not a cert issue)

If I could just get a ‘that should work’ I can have look through the code, but if it’s for some reason not supported I’d rather not waste time…
