how do i find a string in a table?

Hey. I want to search a table for a string. I already tried table.find(table, string), but it always spits out nil.

heres the table:

local emojis = {
	--Standard emoji set
	["standard"] = {
		
		["common"] = {
			
			["Grinning_Face"] = {
				Name = "Grinning face",
				Emoji = "????",
				Rarity = "Common",
				Cost = 50
			},

			["Beaming_Face"] = {
				Name = "Beaming face",
				Emoji = "????",
				Rarity = "Common",
				Cost = 50
			},

			["Grinning_Squinting_Face"] = {
				Name = "Grinning squinting face",
				Emoji = "????",
				Rarity = "Common",
				Cost = 60
			},

			["Smiling_Face"] = {
				Name = "Smiling face",
				Emoji = "????",
				Rarity = "Common",
				Cost = 40
			},

			["Laughing_Face"] = {
				Name = "Laughing face",
				Emoji = "????",
				Rarity = "Common",
				Cost = 70
			},

			["Winking_Face"] = {
				Name = "Winking face",
				Emoji = "????",
				Rarity = "Common",
				Cost = 70
			},
			
			["Cheeky_Face"] = {
				Name = "Cheeky face",
				Emoji = "????",
				Rarity = "Common",
				Cost = 70
			}
			
		},
		
		["uncommon"] = {
			
			["Angel_Face"] = {
				Name = "Angel face",
				Emoji = "????",
				Rarity = "Uncommon",
				Cost = 180
			},
			
			["Goofy_Face"] = {
				Name = "Goofy face",
				Emoji = "????",
				Rarity = "Uncommon",
				Cost = 170
			},
			
			["Star_eyed_face"] = {
				Name = "Star eyed face",
				Emoji = "????",
				Rarity = "Uncommon",
				Cost = 150
			}

		},
		
		["rare"] = {
			
		},
		
		["very_rare"] = {
			
		},
		
		["extreamly_rare"] = {
			
		},
		
		["mega_rare"] = {
			
		}
		
	}
	
}

and this is my code:

function emojis.GiveEmoji(PlayerName, Emoji)
	print(table.find(emojis, Emoji))
	if table.find(emojis, Emoji) == nil then
		print("invalid emoji name")
	else
		local invGui = game.Players[PlayerName].PlayerGui:WaitForChild("Inventory")
		if invGui.Frame.ScrollingFrame:FindFirstChild(Emoji) then
			local Em = invGui.Frame.ScrollingFrame[Emoji]

			Em.Count.Value = Em.Count.Value + 1
			Em.TextLabel.Text = Emoji.." x"..Em.Count.Value
		else
			local clone = invGui.InvContent.ImageButton:Clone()
			clone.Name = Emoji
			clone.TextLabel.Text = Emoji
			clone.Count.Value = 1
			clone.Parent = invGui.Frame.ScrollingFrame
			clone.Visible = true
		end
		print("gave emoji ".. Emoji.. " to ".. PlayerName)
	end
end

and if you are wondering why the function name is emojis.GiveEmoji: its because all of this is in a module script. I hope someone can help, thanks in advance!
