Add configuration options for notifications

**Description**
Currently helpers lacks proper timeout support.

**Proposed solution**
Add configurable timeout with sensible defaults.

**Priority**: Low/Medium

Start by locating the notification helpers and checking how timeout behavior is currently handled. Clarify which notification paths need configuration and what default timeout is expected. Done means the timeout is configurable with sensible defaults and the affected notification behavior is covered by the project's relevant checks.
