Managing Signals
Go to Setup > Channels > Signals > Manage Signals.
The Manage Signals page displays the available custom signals.
Click the more options icon near the signal that you want to edit.
You can edit or delete the signal, view the webhook API of the function that triggers the signal, or edit the function.
These options are available only when your signal is triggered by a function. If your signal is triggered by an API, then you can only see the options Edit and Delete.
