Important points
Instead of directly using the shapes layer from Lottie, a solid region layer is used and is masked(using masks) to draw a circle. This is done to support the invert parameter from Synfig.
The mask is drawn according to: https://github.com/synfig/synfig/blob/678cc3a7b1208fcca18c8b54a29a20576c499927/synfig-core/src/modules/mod_geometry/circle.cpp
