## About this task

An event filter uses conditions based on application name, URL, or window name to identify what activity to capture. Filters support multiple conditions combined with `AND` or `OR` logic.

You can add exceptions to exclude specific screens or pages within captured applications, for example, to avoid collecting data from password fields or payroll screens.
