Map tag with particular Component

[natgeo89]

I need to use particular React Component for JsonRTE entry.
My goal is to receive raw data from contentstack, and then for ol tag use <List>...</List> component with predefined logic and styles. But it is impossible with contentstack SDK / utils:

  jsonToHtml(jsonEntry, {
    customElementTypes: {
      ol: (attrs: string, child: string, jsonBlock: any, extraProps?: object) => <List>{child}</List>,
    },
  });

Callback for ol should always return a string...
How I can resolve this issue? Why there are no any proper utils for that?
