If you specify a value for <code>MaxResults</code> and you have more account IDs than the number that you specify
for <code>MaxResults</code>, Firewall Manager returns a <code>NextToken</code> value in the response that allows
you to list another group of IDs. For the second and subsequent <code>ListMemberAccountsRequest</code> requests,
specify the value of <code>NextToken</code> from the previous response to get information about another batch of
member account IDs.
