Disable Auto init from DOM

I'm mainly using simplebar-react, but in one specific case I also have to initialize simplebar via vanila JS package.

Before extracting simplebar-core as separate everything was working fine because of SimpleBar.instances check. But right now I'm getting 2 scrollbars instead of 1.

So, is it possible to add an option to disable auto init from DOM elements? or disable MutationObserver after initialization?

Start by tracing the SimpleBar.instances check and the MutationObserver behavior in simplebar-core, focusing on how simplebar-react and the vanilla JavaScript package initialize the same DOM element. Clarify whether the requested option should prevent automatic DOM initialization or disable observation after initialization; done means one scrollbar is created without breaking normal automatic initialization.
