Keycloak support for older browsers/WebViiew

Since this issue has been resolved, all cookies has samesite set, some to none.
Our product needs to support older android devices that uses android 8, which does not yet support samesite=none, which results in cookies not being sent, and cookie_not_found error.

Is there anyway to add a flag keycloak to support older browsers?

For reasons, Keycloak won’t support old and insecure environments.
