[NextJS] Hi ! We recently started using

cookieDomain

because we realised that the cookies were not sent in SSR requests outside of dev environements, and are having issues getting sessions to work again. Our frontend/ssr is behind

home.sandbox.domain.io

, our backend is behind

api.sandbox.domain.io

. We've set

cookieDomain: .domain.io

. Should we have set

.sandbox.domain.io

? edit: currently trying to add `sessionTokenBackendDomain`in the frontend
