How to get PlayersGuis of all players

Good afternoon Please tell me how I can get the PlayerGui of all players. I use this:

for i, Player in pairs(game.Players:GetPlayers()) do
end

But it is collected by PlayerGuis partially.

local Guis = {}

for i, Player in pairs(game.Players:GetPlayers()) do
         Guis[Player.Name] = Player.PlayerGui
end
local Players = game:GetService("Players")

for i, Player in pairs(Players:GetPlayers()) do
	local PlayerGui = Player.PlayerGui
end
