CI4 Sheild, cookie expiration change not working

Cannot reproduce.
I get a cookie like this:

Code:

ci_session=11f0a0pefejn9bcs34ktlajce8dpjh07; expires=Tue, 26 Aug 2025 22:55:19 GMT; Max-Age=31536000; path=/; HttpOnly; SameSite=Lax

PHP Code:

--- a/app/Config/Session.php
+++ b/app/Config/Session.php
@@ -40,7 +40,7 @@ class Session extends BaseConfig
      * The number of SECONDS you want the session to last.
      * Setting to 0 (zero) means expire when the browser is closed.
      */
-    public int $expiration = 7200;
+    public int $expiration = 60 * 60 * 24 * 365;
