reference:scripting_reference:scripting_events:onstartup

The OnStartup event can be implemented by a script add-in to receive notification when Opus starts up.

Method Name: OnStartup

Argument Type:

StartupData 

Return Type:

none

Description:

This event is only triggered when Opus starts up, therefore only script add-ins that are already installed will receive it. If a script is installed when Opus is already running it won't receive OnStartup until the next time Opus is started.
