Is possible one time finish the videoconference cancel the link of meeting?

Hi, I’ve created chat for videoconference we will have 20th may, I’ve send link to the relator for our connecting and we still use this chat, even if we go out, the day after we click on the link, we connect.
My question is: is possible one time finish the videoconference at 20th may, to cancel the link of meeting?
Thank you for answer.
