Economics and Permissions

First of all. I love the plugin.
I have the following problems on our server.

How to set the economics to be used. No money will be withdrawn at the moment.

2nd can you only use crafts.use with "Permission (ex: crafts.use)": "crafts.use"?
I tried to use Heli1.use which is also a group of us but nothing shows up. No items nothing.
Is it even possible to integrate your own groups into crafts or not?

I hope to get an answer.

Problem was solved together with the creator. If there is no monument marker with the card reader, the whole thing doesn't work

  "Economy": {
    "Show Balance": true,
    "Type (Plugin/Item)": "Plugin",
    "Plugin name": "Economics",
    "Balance add hook": "Deposit",
    "Balance remove hook": "Withdraw",
    "Balance show hook": "Balance",
    "ShortName": "scrap",
    "Display Name (empty - default)": "",
    "Skin": 0
  },

I'm sorry but it doesn't work that way either.I'm sorry but it doesn't work that way either.

Can you please tell me how it works and what's wrong with it?
