With this query:

supabase
    .from('ingredient-prints')
    .select(`token,
        ingredients(key)
    `)
    .in('token', tokenIds)

i'm getting back this response:

{
    token: '3YXoTg2JT6Qb9m4P6wd2FYP9fFUoeTCt4KLK6BmpsFgf',
    ingredients: { key: 'doom-chalice-holo' }
  }

Is there a way to get them like this?

{
    token: '3YXoTg2JT6Qb9m4P6wd2FYP9fFUoeTCt4KLK6BmpsFgf',
    key: 'doom-chalice-holo'
  }

(basically making the joint table column be at the same level)

You will need to do this in your own code
