Calling Project script from tag value change event script Ignition V7.9

How can I call a project script from a tag value change event script ignition version 7.9.
project script file= utility
project function= insert
Tag Value change event script using-
project.utility.insert()

Tags are global resources, they don’t belong to a project.

In 7.9 and prior you can only call scripts in the global namespace from a tag change script.

In 8.0+ you can only call scripts in whatever is defined as the Gateway Scripting Project from a tag change script.

If you absolutely need to do this from within a project, use a tag change gateway event in the project instead of the event script on the tag.
