Enable preview of bricks as images / icons
Since v3.5.0 you can provide an image URL and an icon component for each brick, so that your editors can select bricks visually when adding a new brick.
By default these features are disabled, as we don't know if you have the preview images / icons.
To enable them you can use the
enablePreviewIcon flags in the Configuration and create the previews to set in the bricks' schema.
