Defaults traits for link block

[MisterFK]

Hi, Is it possible to update a basic-block traits? I try to select by default the option "this window" and delete the other option.

Thanks for your help !

You can update any aspect of the block

const linkBlock = editor.BlockManager.get('link');
linkBlock.set({
    content: {
        ...linkBlock.get('content'), // current content
        traits: [...],
    }
})
