How would you go about importing animations from unity into roblox studios

I recently found some assets in the Unity Asset Store that I am interested in using for a game. I got the models successfully imported into the game, but how would I go about importing the animations?

These are some of the animations I want to upload.

You can use some conversions. But it’s up to you.

All i want to do is to convert Roblox Animations to Unity in order to make it more simpler and clean, rather than using a lot of transforms in Unity to adjust the Animations. But quite impossible for this situation.
