How does one get the already instantiated instance of the Editor JS by its id value when there are two or more instances of editorjs running in the same browser?

How does one get the already instantiated instance of the Editor JS by its id value when there are two or more instances of editorjs running in the same browser?

Currently ```const editor = new EditorJS({ holder: "my-id"});``` - I no longer have access to the ```const editor``` property, so I would like to use the id "my-id" to get hold of the instance. I'm struggling to find documentation to confirm or reject if this is possible. I do hope it's possible to do this?

Many thanks.
