How to check if certain Role can use command

Hello,

I’m making Command Handler but I have problem with checking specific Roles in command.

Here is script with commands:

local Players = game:GetService("Players")

local roles = require(script.Parent.Staff)

local function isInGame(PlrName)
	for i, plr in pairs(Players:GetPlayers()) do
		if string.match(plr.Name:lower(), PlrName) then
			return plr
		end
	end
	return nil
end

local commands = {}

commands.speed = {
	Name = "Speed",
	Desc = "Set Player WalkSpeed",
	Aliases = nil,
	Roles = {roles.Owners}, -- roles that can use this command.
	Run = function(sender, args)
		local PlayerName = isInGame(args[1])
		local amount = args[2]
		
		if PlayerName and amount then
			PlayerName.Character.Humanoid.WalkSpeed = amount
		else
			warn("Player isn't in Game")
		end
	end
}

return commands

Here is script with roles (module):

local staff = {}

staff.Owners = {
	["Simon"] = 1583088521,
    ["Rosh"] = 226087810,
}

staff.Developers = {}

staff.Managers = {}

staff.Admins = {} 

staff.Partners = { --Requirement: nil

}

return staff

I don’t have any idea how to check Roles that can use specific commands.

if table.find(Roles, player) then
  --
end

Something like this could potentially work.

It won’t work.
Names in brackets aren’t real, they are only there to know whose user ID it is

if table.find(Roles, player) then
  --
end

It will continue the function when it will find an Player name in Roles tables.
