Fibery Automations and scripts unfortunately have no ability to control the UI - the most they can do is display a “result message” (and Button scripts can also send info to the browser’s debug console). Automations can also create Notifications, but that is not quite the same.
I doubt a script could create a clickable link in a Button result message, since these messages do not support any HTML or formatting.
I’m not sure if this is still relevant to anyone, but it turns out you can create user notifications using Graphql mutations and execute them using fibery.graphql() in scripts and automations. I’ve been able to generate user notifications with both automations and buttons. There are some good examples here: . | Fibery.
Given that you provide an entity to send the notification about, I figured that you could filter for the new entity that was created and send confirmation as a notification. When you click on the notification it opens the entity in question. I realize it’s not a direct link in the traditional sense but it does provide the user with easy access to the new entity.
