When trying to init a theme and passing partial options, TypeScript throws an error because the theme and styles properties are marked as required in the interface CreateThemeOptions. This can be reproduced with the following:

import { materialInit } from '@uiw/codemirror-theme-material';

<CodeMirror
  theme={materialInit({
    settings: {
      caret: '#c6c6c6',
      fontFamily: 'monospace',
    }
  })}
/>
