I didn't include models because the models used are not mine. Are you sure you can't retarget the animation to another model in Unreal? I can't really test it in Unreal as I don't use it, but from what I've seen and heard online you can retarget an FBX animation Rig to another model in Unreal using a T-pose.
I found this online let me know if this helps or if you need anything else: https://docs.unrealengine.com/4.27/en-US/AnimatingObjects/SkeletalMeshAnimation/...
Thank you for your reply. Unfortunately we can't import the fbx files into unreal engine, it doesn't allow us to do so. So we're already blocked at import time, so it's impossible to modify them inside the software.
When you import them (even the T pose) you get the error message: "Error Mesh contains Hips bone as root but animation doesn't contain the root track".
I spent a good 2 hours trying to debug the problem online, but I ended up with videos that show us in summary how to import mixamo animations to unreal engine, and each time they already have a reference model for the animations.
That's why I'm quite disappointed, I'd seen a lot of comments about Unreal engine, but I don't know if they've really succeeded in importing the animations.
As mentioned before, I don't use Unreal so most of my knowledge on Unreal is second hand, but this is all I can give you regarding that error, I hope this can help you fix it:

Is it perhaps feasible for you to provide the animations along with a freely available and royalty-free mesh or model, akin to the approach on platforms like Mixamo? I've attempted the tutorial without success and subsequently explored Fiverr to enlist someone's assistance in resolving the issue. However, two sellers conveyed a similar message—stressing the need for a mesh for successful conversion to Unreal Engine. Both noted that the existing bones are not humanoid, leaving me somewhat perplexed and finding the process rather challenging.
If you could assist in reconfiguring the animations onto a model, I would be inclined to approach Fiverr's 3D artist sellers to retarget them for Unreal Engine. Following this, I could provide you with the models. This approach would potentially enhance your sales, as the models would officially be compatible with Unreal Engine.
