Sometimes you create a Package link but decide not to include an Expiration Date so it will always be accessible. Changed your mind ? Here is how to keep your Package in your Packages list but disable its link so it won't be accessible anymore.
Go to the Packages section in the toolbar on the left of the screen.
Click on the three dots in front of the package in question.
Under the Link tab enable the Expiration date option and choose a near date.
Click on Update to confirm & finalize.
The Package link will expire after that date and will no longer be accessible outside of your workspace.
