When you complete recording a video, the share link for that recording is automatically copied to your clipboard. You can paste the link anywhere and share it. In case you want to get the link sometime later, it is easily accessible via the Copy link button at the top right of the page.
Before sharing if you want a preview of your video, you can do it by the "View Recording" option located to the right of the "Copy Link" button.
If you want more sharing options, you can click on the Share tab for that recording. Here, you will see the various options for sharing your recording.
