How to know when a data ting is used or not by an application?

I made some changes in my app and I would like to know, if any one of the data things were left unused.
How can I do this? Is the any easy way?

Using the app search tool.

Top right of the editor you should see a magnifying glass :mag_right:

Use that to search for the thing and you can see if it’s used on any page or not.

Thank you.
