* ### Update ordering of fields on an existing metaobject definition

  #### Description

  To update the ordering of fields on an existing metaobject definition, use the \`metaobjectDefinitionUpdate\` mutation with the \`resetFieldOrder\` boolean.

After the update, the ordering changes to "hex", "name", and "accent\_color".
