Display Error When Adding Beyond the Maximum Limit to the Calendar

According to the technical information provided, there is a limit to the number of additional users that can be added to a Notes calendar. Currently, if a user attempts to add beyond this limit, no message is displayed and the users who exceed the limit are not shown.

I would like to request the implementation of an error popup, such as "You have exceeded the maximum number of registrations," when attempting to add beyond this limit. Having a popup would allow users to understand that this limitation is due to the product's specifications. Currently, it appears as though additions are being made without error, which can be misconstrued as a malfunction.
