How to set headers after the client has been initialised ?

Hello, how to set headers after the client has been initialised ?

You can do this via plugins like this Auth header example here.

Or you can also use context object while creating the query or mutation:

const { execute } = useMutation(`mutation { test }`, {
  context: {
    headers: {
      'someheader': 'value'
    }
  }
});

const { execute } = useQuery({
  query: '{ test }',
  context: {
    headers: {
      someheader: 'value',
    },
  },
});

The latter approach isn't documented, I will make sure to add it.
