Support notifications configuration

**Description**
Currently lib lacks proper compression support.

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

**Priority**: Low/Medium

Start by inspecting the lib directory and locating any existing notification, configuration, and compression-related entry points. Clarify whether the requested change concerns notifications or library compression, then define sensible defaults and verify the behavior with the relevant existing checks or a focused test.
