If there are no options when adding a Display Capture
This is due to a Catalina security bug, try the following:
Open Terminal, and run:
cd /Applications/EBS.app/Contents/Resources/bin && ./ebs
cd /Applications/EBS.app/Contents/MacOS && ./ebs
In System Preferences, go to Security & Privacy. Click the Privacy tab, and find Accessibility. If EBS or Terminal is listed there, make sure it is checked.
