How can I share inventory on my channel to Roku

Hi,

I’m a new developer for Roku.

While I’m studying RAF, I have a few queries for sharing inventory from my channel to Roku.

  1. on the Client Side Ad Insertion.

How can I share 30% of inventory to Roku?

Should I control it by calling setAdURL() and setAdURL(“with my ads server”) by counting it in the app?

  1. On the Server Side Ad Insertion,

How can I share 30% of inventory to Roku?
Is there any Roku ad server url? which can be call from my SSAI vendor setting?

Even I tried to find the answer for above query on document or forum, I can not find it clearly.
