I encountered this problem and I don’t know how to solve it. I don’t understand the documentation very well.

This should work I think? https://docs.plasmo.com/framework/ext-pages#adding-a-side-panel

@louisgv Not exactly because API for sidebar looks like this:

"sidebar_action": {
	// Required
	"default_icon": "icon.png",
	// Optional; shown in tooltip
	"default_title": "My Sample Extension",
	// Required
	"default_panel": "panel.html"
}
