 KRKNWK-16728: Sleepy device may consume much power when commissioned to a commercial ecosystem
  The controllers in the commercial ecosystem fabric establish a subscription to a Matter device's attributes.
  The controller requests using some subscription intervals, and the Matter device may negotiate other values, but by default it just accepts the requested ones.
  In some cases, the selected intervals can be small, and the Matter device will have to report status very often, which results in high power consumption.
 
  **Workaround:** Implement ``OnSubscriptionRequested`` method in your application to set values of subscription report intervals that are appropriate for your use case.
+ Additionally, register your class implementation to make ``InteractionModelEngine`` use it.
  This is an example of how your implementation could look:
