Custom field settings

Another way is to put your configuration to the options.

// src/plugins/yourPluginName/admin/src/index.tsx

export default {
  register(app: any) {
    app.customFields.register({
      name: fieldName,
      // ....
      options: {
          advanced: [
          {
            name: "options.color",
            type: "string",
            defaultValue: "#000",
            intlLabel: {
              id: `${pluginName}.${fieldName}.options.advanced.color`,
              defaultMessage: "Color",
            },
            description: {
              id: `${pluginName}.${fieldName}.options.advanced.color.description`,
              defaultMessage: "You can set the color here",
            },
          },
      }
 // ....

And then in your Component you can access on this option like this

export function YourCustomField(props: Props) {
  const { attribute } = props;
  return <div>{attribute.options.color}</div>
}
