Has anyone retrofitted a power hatch into a CX-5?

:
2010 Mazda 5 Sport
My mom has a CX-5 and the lift gate is just heavy enough that it is bothering her aging hands. The Mazda 5 she used to have was fine as it's rear hatch was lighter/better balanced and we never figured the hatch in this CX-5 would be an issue.

I see a hew retrofit kits on Amazon, etc but none have ratings.

We don't care about a key fob or inside cabin button, just that when she pushes the button on the hatch it opens unassisted.
