How to change control settings through UMG?

Hi, i’m building a main menu and a pause menu

so i’m trying to change control settings (action & axis mappings) through UMG

but i couldn’t find a way or a reference like the provided “Scalability Reference” here :
https://docs.unrealengine.com/latest/INT/Engine/Performance/Scalability/ScalabilityReference/index.html

so how exactly could i achieve this ?

just found a solution by Rama

you need to download Rama’s UMG Rebindable Key System project (check out the latest updates here) :

alongside the “Victory” plugin here :
