Meeting SDK dynamic feature :mobilertc integration —on demand SDK install

Meeting SDK Type and Version
I recently downloaded Zoom Meetings Android SDK latest package v6.1.1.22760

Description
Since previous iterations, Zoom Meetings Android SDK comes with dynamic_sample & feature_mobilertc folders which lets you get the Meeting SDK delivered as an optional package after the app is installed.
I want to enable this functionality for the app users, so that they can use the SDK features as per their choice at the time of app installation.

I cannot understand the official zoom documentation on integration part for same.
Please assist with any other tutorials or step by step procedures on how to integrate the dynamic feature module to enable the on-demand sdk install feature and make use of it for the best user experience.
