LuxuAdmin allows you to add custom buttons with any functionality you would like.
Information:
Open LuxuAdmin/custom_functions/client.lua
Create a new entry inside the Custom_buttons table
Custom_buttons = {
   { name = 'Example Button', event = 'LuxuAdmin:ExampleCustomButton',  category = 'players' },
  }
Create the NUI event handler with the event we defined above
--- the "targetSvId" is only valid if the button is de
RegisterNUICallback('LuxuAdmin:ExampleCustomButton', function(targetSvId, cb)
      -- Check if the admin has permission to use this button
      -- Remember luxuadmin.custombutton is just an example ace permission
      -- You decide what to name this button's permission
      if not CheckPerm('luxuadmin.custombutton') then
            cb(false)
            return
      end
      print(string.format('Example function, Target Player Server ID: %s', targetSvId))
