Low poly tree swaying

Hello, could someone tell me how I can make this low poly tree sway in the wind? I would like to make it move depending on different weathers in the future but for now I just want a simple animated sway, unless rigging it to get a simple sway is just the same as rigging it for weather effects of course, I have no idea where to start and there’s not really any tutorials I can find on low poly stuff like this, the only tutorials I’ve been able to find for tree sway cover high detailed ‘sapling’ trees, which is not what I’m doing. Thanks!
