Using default-field-editors with multiple locales

I made some progress on building a custom editor UI with the default field editors. It works already great when using a single locale.

However, selecting mutliple locales in the sidebar, I cannot find any documentation on how to pass the locales into the default field editors. The UI should look like the standard editor UI provided by Contentful.

I’m currently using the Field and FieldWrapper like documented:

    <FieldWrapper sdk={fieldSDK} name={name} showFocusBar>
       <BasicField sdk={fieldSDK} />

How can I pass in multiple locales? It’s not part of the FieldExtensionSDK type neither.
