You can edit an existing launch definition by changing its values in the details pane. Do not directly edit launch definitions that begin with SPO.
To edit an existing launch definition
With the External Applications node selected in the navigation pane, click the desired launch definition(s) in the display pane.

Note: You can test the launch definition before you save it. Once it is saved, it is available to all users.
Tip: You can make the same change to multiple launch definitions at one time by first selecting all the desired definitions in the display pane. The common properties for the selected definitions are displayed in the details pane. Make the desired change and it is applied to all selected launch definitions.
