To enable round brackets " ( ) " to be used

To enable round brackets " ( ) " to be used in username when guests join Webex meetings.

When a guest user joins a particular meeting, they have the option to input their name upon entering. If their name contains round brackets - '( )', the parentheses symbol will not appear in the meeting.
E.g. If the user types Peter Pan (Support), his name will be changed to 'Peter Pan Support' in the meeting.

Other parenthesis symbols, such as square '[]', curly'{}' and angle'<>' brackets are still available to use, but we would like to ask to make the round brackets "( )" available.
