Display concatenation of object schema field in Sanity Studio instead of last item

I'm quite new to Sanity and I'd like to know how to do this.

I'm adding items using the following schema

defineField({
    title: 'Ingredients',
    name: 'ingredients',
    type: 'array',
    of: [
        {
            type: 'object',
            fields: [
                {
                    name: 'ingredient',
                    title: 'Indredient',
                    type: 'reference',
                    to: [{ type: 'ingredient' }],
                    validation: Rule => Rule.required().error('Ingredient is required.')
                },
                defineField({
                    title: 'Amount',
                    name: 'amount',
                    type: 'number',
                    validation: Rule => Rule.required().error('Amount is required.')
                }),
                defineField({
                    title: 'Unit',
                    name: 'unit',
                    type: 'string',
                    options: { list: [...] }
                })
            ],
        }
    ]
}),

This works fine, but when adding the entity in Sanity studio it only shows the last item in the object like this

How do I get this to display with a concatenation of the object values?

You need to add a list preview after the fields array. You can find more help in Sanity docs here: https://www.sanity.io/docs/previews-list-views
