Here are some duplicated actions, maybe we could reorganize them like this:

manageSessionStorage(key: string, value?: string): void {
  if (window.sessionStorage) {
    if (value !== undefined) {
      window.sessionStorage.setItem(key, value);
    } else {
      window.sessionStorage.removeItem(key);
    }
  }
}

const USER_POST_AUTH_ROUTE = 'USER_POST_AUTH_ROUTE'

manageSessionStorage(USER_POST_AUTH_ROUTE, storedRoute); 
manageSessionStorage(USER_POST_AUTH_ROUTE);

Maybe when we reach rule of three
