Retrieve the card_admin_id from GET /api/card-admins/card/:card_id, then submit a replacement privilege object here.

Example:

curl -X PUT "$BASE_URL/api/card-admins/<card_admin_id>" \
  -H "Authorization: Bearer <access_token>" \
  -H "Content-Type: application/json" \
  -d '{
    "privilege": {
      "can_update": true,
      "invite_contributors": true,
      "admin_management": false
    }
  }'

• Authorization: Bearer <access_token>

Generate the bearer token by:

2. exchanging them at POST /account/api-access/token
