how can i get the scene to load from a from the API

Hi I'm trying to load a scene on my website via a button and tried two ways, neither work

method one:

choose the "Scene remains closed (will be opened by API)" in the embed menu and try load it with "loadScene(9)"

Problem: scene es close on page load, but button don't do anything

method one:

try to add minimize button, load minimized and maximize it with "overlayOpen(‘max’)"

problem: minimize button don't show up and cant find option to load scene minimized

i don't want the scene load from the start, i want it lo load when someone click the help button
