eSDK and content search in companion app

[rogfan]

Hello,

we are planning to create a hardware device which should play content autonomously via the eSDK. The hardware will have a companion app where we intend to integrate Spotify streaming into an enriched audiovisual user experience. 

We find the documentation in that regards a bit misleading. Is there an allowed way to integrate the Spotify search from the WebSDK within the app to play content through the official native iOS / Android Spotify apps on our created hardware?

Secondly, is it possible to directly set our hardware as the player of the content triggered via our app and channeled through the official native iOS / Android Spotify apps?
