Requirement for custom Zoom Meeting app for Embedded device

Hi. My company try to sale android based embedded devices.
And I want to preload custom Zoom Meeting (Only meeting feature) app with Meeting SDK.

  1. Do I need to contract ISV program for this usage?
  2. As far as I know that I can build and publish (preload the app into my embedded devices) the app after reviewing without any fee.
    Zoom basic user can join the meeting, and Zoom pro user can create the meeting room after login, right?
