query parameters for dynamic config

Question 💬

As shown here: #2688
I can wrap NextAuth function, which gives me a chance to dynamically change the config via GET parameters. The end goal for me is to do login through Shopify that is non-standard, where the URL requires the shop name like so:

 authorization: {
          url: `https://${shopName}.myshopify.com/admin/oauth/authorize`,
          params: { grant_type: 'authorization_code', scope: 'read_customers' },
        },

unfortunately, NextAuth triggers a redirect which makes me lose the GET parameter. Also, is this the recommended way of doing it? I looked into signIn() and I do not think I can override the URL through that function? If so, I think that would be more ideal.

How to reproduce ☕️

export default async function auth(req: NextApiRequest, res: NextApiResponse) {
  const { shopify } = req.query
  console.log('REQ: ', req.query)
  return await NextAuth({
...
