[Feature]: More options how to filter click events

[krystofmatejka]

Is your feature request related to a problem? Please describe.

If you have APP 2 as a part of APP 1, there isn't any possibility of collecting clickanalytics events only from the inner (APP 2) application.

dntDataTag works the other way around. You can apply it to APP 2 and prevent APP 2 from collecting metrics.

Describe the solution you'd like

1. I would implement filter callback that would be called when the event is processed. If the callback returns false, the event will be dropped.

Proposed interface

export interface IValueCallback {
  dropEvent?: (event: ITelemetryItem): boolean;
}

2. Or we can introduce something like dontDntDataTag attribute that would capture events only from elements that have this parent attribute. You would apply it on root element of APP 2 and everything from APP 1 will be ignored.

Describe alternatives you've considered
My current solution is to filter events by parentId in KQL.

Additional context
If it makes sense to you, I'm willing to implement it.

one workaround is set parentDataTag

ApplicationInsights-JS/extensions/applicationinsights-clickanalytics-js/src/Interfaces/Datamodel.ts

Line 83 in 767790b

parentDataTag?: string;

of App2 to a different one, and mark app1 as do not track. please let us know if it works!
