I need to trigger a survey from a button in Workspace.

[SiripriyaP]

I have created a survey. now I want to know how to trigger a survey from the notification. generally we do it using trigger conditions, it will be creating a new assessment instance. how can I achieve it?

Use notification email script to generate an assessment instance for a specific record.

Define the survey, create a trigger condition, and use script logic to link the survey instance to the current incident or case table etc.
