Code Block missing after changing the default programming language

[fedenuche]

I'm trying to change the default programming language in the Code Block from Javascript to Python. So I'm using the customizeCodeBlock function, but when I use that, the block disappears from the slash menu.

import {
  BlockNoteSchema,
  defaultBlockSpecs,
  customizeCodeBlock,
} from '@blocknote/core';

const schema = BlockNoteSchema.create({
  blockSpecs: {
    ...defaultBlockSpecs,
    codeBlock: customizeCodeBlock({
      defaultLanguage: 'python',
    }),
  },
});
