How to programmatically open the app-navigation?

On small screens, the app-navigation is hidden by default. I need to open the app-navigation from my app’s JavaScript code in a special situation. Unfortunately, the snapper object (Snap) is not accessible from here, see https://github.com/nextcloud/server/blob/1bb552761b6740833ba28638b2e5e1e3dcebc705/core/js/js.js#L1605

Is there a way do this anyway?
