urql does not set fetch options

[gbahsa]

Hi,

I am using the new Next.js App router and an Graphql API in backend.
When the query is run, I always have 401 Unauthorized. For your information, I set the fetchOptions property as it's mentionned in the doc. Having a look in the console log, I have noticed the Authorization key in headers is not set.

Is there something I did wrong ? Thanks for your help.
