The function "Invite guest to meeting" is really useful, especially for internal calls or webex team meetings, as often in the middle of a meeting you realize that the input of someone who was not invited initially would be useful now.
If the just invited person has time to join, the feature is great. If the invited user does not respond immediately he/she still sees the ongoing meeting all time and can join till the meeting has ended, no matter if the particpants in the meeting still need the input or not.
This often leads to the fact, that invited people jump into the meeting, when the meeting has already moved forward in the agenda and where in same cases, maybe even sensitive info might already be discussed.
It would be great, to have a possibility to cancel or withdraw the invitation either manually at any time if the user does not join, or to stop it automatically e.g. if the user does not join after 1 minute.
