Window.open but I want to openSidePane

Hello, trying to code something like :

window.open(iframeSrc, "_blank");

but I’m trying to window.openSidePane or something like that which would open window in the pane on the side or create one if none exist yet

Has anyone figure this out? Any help would be truly appreciated. Not even sure this is possible since browsers don’t usually have side panes

I’ve tried changing "_blank" to the others options but it kept the same functionality ["_self", "_parent", "_top", ... ]
