How can I set starting/ending size in Grow/Shrink animation?

OS version: Fedora Linux 41 (Workstation Edition)
App version: 8.2.2-22.el7
Downloaded from: ONLYOFFICE website
Additional information:
I would like to use the grow/shrink animation to start an image at twice its actual size and shrink it to actual size. However, after creating the animation, the “Parameters” menu is grayed out:

Is this expected behavior for this application? If so, what can I do to set up this animation correctly?

Hello @flavonol

This animation does not yet have parameters for configuration, unfortunately. We are working on various animations and their configurations, animation Grow/Shrink is also in this list. They will be added in future releases of Desktop Editors.

Sorry for the inconvenience.
