Add Commands to admin panel

I want to add to this panel option to add currency and items to a player when they are not in game & are in game

And it will send message to them “You recieved the following items:”

I don’t know how to do it and if someone can help I’ll appriciate it so much, It’s really important to me

Video & Model:

you can use <PlayerInstance>.Chatted:Connect(function(msg)
