This activity cancels “Block input” and enables the user’s input.
This parameter allows you to create an annotation to the activity. The input text will be displayed above the activity name.
There are no other specific parameters for this activity. The only valuable thing is the position of the activity in the workflow.
How to use it?
“Unlock input” is the reverse of “Block input”.
If you have the "Block input" activity in your workflow and at some point an input from the user is required, the “Unblock input” allows you to let the user interact where needed.
Here is a typical case of implementing “Unblock input” in the workflow:
This workflow blocks the input as execution starts, opens the browser, then lets the user input some text, then blocks the input again to execute further steps.
