Greetings @Kri. The only thing I'd like to add to @Dr Atul G- LNG's amazing comment is some screenshots of how ServiceNow generates a Code Snippet for you to copy and paste into your UI Action.
- Navigate to either Flow Designer or the new Studio.
- Click on the Actions tab / pill
- Select the Flow Action you wish to call from your UI Action. In my example, I picked the "Add Comment" Flow Action
- Within the Flow Action, navigate over to the upper right of the screen to the More Actions menu icon. In the menu that is displayed, select Create code snippet.
- A pop-up will then display that says Code snippet to execute this Action. Click the blue Copy Code Snippet to Clipboard button at the bottom of this pop-up.
Finally, all that will be required after that is to map any inputs for the Flow Action from the UI Action into the generated code snippet.
I hope this information is helpful!
