getSession() call for 'better-auth/client' isn't increasing the session expiry. so, basically if the session expiresIn is set to 120 and the updateAge is set to 30 , then no matter how many times the getSession() is called, the session expiry isn't extending, and becomes null after 120 seconds. in the network calls also I didn't observe anything except api/auth/get-session calls.But whenever the session is used and the updateAge is reached, the session expiration is updated to the current time plus the expiresIn value.
