Non-linear ads support?

I’ve worked a bit with delivering Non-linear (overlay) ads for web browser players with VPAID through VAST (VPAID allows a Flash/JavaScript ad manager to be delivered to the player which gathers data and controls loading a Linear or Nonlinear ad).

Is there any support for Non-linear ads on Roku channels? I’ve seen “Interactive Ads” mentioned in the docs, what are these?

As of current version (2.3), RAF supports interactive ads by Innovid or BrightLine, typically microsite when clicking on CTA button or TrueX
