Custom name of primary key (add primary props for field)

[alexdeia]

Hello.
I read the docs https://payloadcms.com/docs/fields/overview#customizable-id about it, but it only describes changing the type, not the name. How can I do it?

Expectation:
Possible to rename id field to, for example, identity and this field will become the new primary key.

...
  fields: [
    {
      name: 'identity',
      type: 'text',
      label: 'Identity',
      unique: true,
      required: true,
      primary: true, // -> THIS for example
    },
    {
      name: 'description',
      type: 'textarea',
      label: 'Description',
    },
  ],
...
