Removing a user context

Consider a scenario where you have a WebDriver BiDi connection and an active session. After creating a user context with browser.createUserContext, send the following message if you want to remove it:

json
{
  "id": 1,
  "method": "browser.removeUserContext",
  "params": {
    "userContext": "4e4b1f6d-3f1a-4b2e-9f8c-1a2b3c4d5e6f"
  }
}

The browser responds with a successful removal as follows:

json
{
  "id": 1,
  "type": "success",
  "result": {}
}
