Please add built-in shape-drawing tools (e.g., rectangle, circle/ellipse) to the Adobe PDF Embed API

Currently, the PDF Embed viewer supports text annotations, highlights, and freehand drawing, but it does not provide simple tools for drawing standard geometric shapes such as rectangles or circles. For many use cases — including document review, form markup, architectural sketches, and technical diagrams — users need to add clearly defined shapes rather than hand-drawn lines.

While it’s technically possible to simulate shapes using custom code and the AnnotationManager, this approach is not user-friendly and tends to produce inconsistent or distorted results. A native, integrated solution within the Embed UI would greatly improve usability and align with the experience in Adobe Acrobat.
