Options for automatically creating keyframes for animation in ArcGIS Pro unavailable

[MatthewLaw]

Does anyone know why some of the options for automatically creating keyframes in an animation in ArcGIS Pro (as per this documentation) are greyed out (the bookmarks and range slider options), and others (the circle around selection options, which is what I want to be able to do) do not show at all (see attached screenshot)? The map is a 3D scene with 3D data, and when the screenshot was taken the camera was viewing at an oblique angle (ie not directly above), and there was a feature selected.

I am running ArcGIS Pro 2.4.2.

All suggestions greatly appreciated!

Looks it may be new functionality within ArcGIS Pro 2.5 release.What's new in ArcGIS Pro 2.5—ArcGIS Pro | Documentation    Look under Mapping and Visualization --> Animation

• Keyframes capture properties about your map and layers when creating an animation. Keyframes have been extended to capture the following additional map and layer properties: visibility and vertical exaggeration for the map's ground and custom elevation surfaces and vertical offset and vertical exaggeration for 3D layers in a scene. You can now animate surface properties, which improves your ability to show changes that were otherwise difficult to observe.
• Animation overlays now support four new graphic shapes available in the overlay gallery: point, ellipse, rectangle, and arrow. These overlays can bring attention to features of interest in an animation. You can also group overlays by adding a new Group overlay and manage the overlays it contains from the Animation Properties pane.
• Improvements for editing an overlay include editing within the map or scene. Drag the handles on a selected overlay to resize and rotate it. You can manually reposition overlays by moving them around the view. Editing controls are still available on the Animation Properties pane for overlays.
• There are new automated methods for creating keyframes to animate in a circle around a particular location or feature. In the Import gallery, four options are available for circling in the left or right direction around either the center of the current camera view or a selected feature. The keyframes are automatically created and added to the animation.
