When creating keys, API docs state we can use regex for the collections.

client.keys().create({
  "description": "Key for searching org collections.",
  "actions": [
    "documents:search"
  ],
  "collections": [
    "org_.*"
  ]
})

Are we free to use any regex? Like can we do:

"collections": [
    "^(?!userFood).*$"
  ]

Ie any collection not starting with

userFood

?
