Ubuntu 22.04 has a new screenshot tool that also includes the screencast (video recording of desktop) option.
When you press the Print Screen button to take the screenshot, it opens the UI and gives you the option to take the screenshot of the selected area, entire screen, or current application window. The screenshots are copied to the clipboard and saved to the Screenshots folder under the Pictures directory.
