Visual Studio: How to detect any changes on project properties and trigger event from extension when user clicks apply

I'm trying to write VS extension (VS Professional 2022 with Version 17.2.6) for VC++ projects, I want to detect any changes on project properties (Additional include directories, additional using directories etc.) when user changes and clicks apply on project properties page.

I don't want to trigger event until user clicks apply. If user clicks, I want to fire an event from My extension. Thanks for your help.

I tried to capture Command Events from EnvDTE but I did not find Command code for Apply button. In the case of clicking apply, VsStd97CmdId will be 684 or 1990. Those are not specific for apply command.

Other thing that I tried was, detecting changes on project file, but Changes are not saved vcxproj file until save or save-all
