I do this often and it works great. You'd need to:

1. Send a message from the process to the front end. See https://customerfx.com/article/how-to-refresh-a-page-from-a-process-in-…
2. Have some code somewhere that listens for the message. See https://customerfx.com/article/receiving-server-side-messages-in-a-crea…
3. Then display the toast message. See https://customerfx.com/article/displaying-toast-message-popups-from-cre…

I've typically done this by making a generic process I can use as a subprocess. It sends the message to the client. Then I make a generic script loaded from MainShell or MainHeaderSchema that listens for the message and displays the toast. It makes it simple and generic to use and works on any page.

Ryan Farley,

How do you go about creating a generic script that loads in the MainShell or MainHeaderSchema in Freedom UI? It hasn't seemed to work when I've tried it.

Harvey Adcock,

You need to add a feature to enable creating replacing schemas for angular modules such as MainShell. See this thread: https://community.creatio.com/questions/how-create-replacing-schema-freedom-ui-basepagetemplate
