How to Add a Custom Main Menu Item in the Editor?

Questions
#1

Hi everyone,

I’m trying to add a new main menu item to the editor’s menu bar, and I have a sample script created with the assistance of ChatGPT. However, the menu doesn’t seem to appear or work as expected. Below is the code I’m using:

local M = {}

function M.get_commands()
  return {
    {
      label = "Library", -- Menu name
      locations = {"Edit"}, -- Not sure what to put here instead of "Edit"
      query = {selection = {type = "resource", cardinality = "one"}},
      active = function(opts)
        return true -- The menu is always active
      end,
      subcommands = {
        {
          label = "New Card",
          active = function(opts)
            return true -- Logic to determine if "New Card" is active
          end,
          run = function(opts)
            print("New card created!") -- Logic for creating a new card
          end
        },
        {
          label = "Collections",
          active = function(opts)
            return true -- Logic to determine if "Collections" is active
          end,
          run = function(opts)
            print("Collections management opened!") -- Logic for handling collections
          end
        }
      }
    }
  }
end

return M

Does anyone know if it’s possible to add a custom main menu entry like this, or what might be going wrong with this approach? Also, I’m not sure what the correct value for locations should be instead of “Edit.”

Thanks in advance for any help!
