Is there any way to add slovakian localization into UE4?

Hi, i need to know how can i put slovakian keyboard layout in UE4. Words like ľščťžýáí (in US layout 23456789).
I noticed that valorant have this ability and why no UE4?
I found this:Unreal Engine Issues and Bug Tracker (UE-34945) with wont fix and i dont understand why.
