Name	Purpose
`Annot`	Annotation dictionary returned by an annotation creation call or held in `LastAnnotation`
`Trigger`	Annotation additional-action trigger to remove

The method removes only the selected trigger entry and keeps other annotation actions unchanged
If the annotation /AA dictionary becomes empty, the dictionary entry is removed from the annotation
Use SetAnnotationAdditionalAction to install a replacement THPDFActionBuilder chain for the same trigger
Use THotPDF form-field action convenience helpers when the target annotation is an AcroForm widget selected by field name
