Update ‘Default’ Block Style

I am trying to programmatically update the default block style of an image block.

When a user updates a custom select dropdown in the editor (using ACF plugin), I trigger a JS function that unregisters the default core/image style, and registers a new one, setting it to the default style.

e.g

wp.blocks.unregisterBlockStyle(
  'core/image',
  [ 'retailResidential', 'weddingsEvents', 'advertisingEditorial']
);

wp.blocks.registerBlockStyle( 'core/image', {
  name: "weddingsEvents",
  label: "weddingsEvents",
  isDefault: true
});

Then when a user creates a new image block, I want the updated image style class (which should be the default), to be automatically applied to the image.

However, this is not working, and I am unable to programmatically update the default style in this way. If I manually update the default style using the ‘Default Style’ select/dropdown it seems to work for adding additional images, but can not do this with JS.

Any help is greatly appreciated. Thank you for reading.
