We recommend deleting connections to data sources you no longer need. This makes it easy to identify which data sources are in use.
Click on your initials in the top right-hand corner.
From the drop-down, select Admin.
Click the Connections tab.
Click the more options icon next to the connection you want to delete and select Delete connection.
By default, deleting your connection to a data source will delete all the associated widgets. If you want to retain the widgets, check the option when deleting the data source.
Click Delete connection again when prompted.
