- `admin` - **bool**, optional, defaults to `false`. Whether the user is a homeserver administrator,
granting them access to the Admin API, among other things.
- `deactivated` - **bool**, optional. If unspecified, deactivation state will be left unchanged.
- `locked` - **bool**, optional. If unspecified, locked state will be left unchanged.
