Need Help With Show UI Command

Guides UI and Macro
1

The addon curseforge com/wow/addons/kills-until-no-rest/files/3309781
It has no way, except to relog to show the UI of the addon, and I want to add the command /kills to make it show. What code would I need to add to the lua file to make this happen? I have no idea what I’m doing. Thank you.

At the bottom of the file add:

SLASH_KILLSRESTED1 = "/kills"
SlashCmdList.KILLSRESTED = function()
	KillsRestedXPFrame:SetShown(not KillsRestedXPFrame:IsShown())
end

Thank you so much!
