How to signal to the host that the plugin settings have changed?

Hello! When the plugin parameters change, the host is notified, so it considers that changes have been made to the working document and, as a consequence of this, offers to save the changes when closing the working file/DAW. But when I change some other settings, such as file names, which are not saved as parameters but their data is saved in chunks, then the host must somehow be notified of this type of change. Please tell me how to implement this if possible?
