Sapling Tree Gen Addon

Hey Guys,
i am currently trying out the Sapling Tree Gen Addon in Blender 2.9 - since i wann use this addon as an alternativ for Speedtree.
I got a few questions:
1.) How do i get keyframes onto the Armature when, I use the Animation Tap of the Addon
2.) How do i get an animated Tree ready for other Softwares like Maya, Unreal etc.
3.) Is ther an option to bake the Animation onto the Armature…

kind regards
