I am presently trying to do ad insertion from a Dash manifest. While I know this could be done with Ad Breaks, I was hoping to catch ad event directly from my manifest. At first I was trying to catch EMSG_EVENT with this manifest but no event where triggered :

I was expecting from this to have 2 events triggered (at seconds 2 and 5). Then I decided to try this manifest directly on Shaka player. I found out that the good events to listen to for this syntax of ad event where timelineregionenter and timelineregionexit. These events are triggered by Shaka when encountering EventStream with sub Event while emsg events are triggered when encountering InbandEventStream. The thing is I don't see any reference of these types of errors in the Cast Framework documentation. I have the impression that CAF event EMSG_EVENT can only be triggered by InbandEventStream.
So, my question : is there anyway to catch timelineregionenter or timelineregionexit events on CAF Receiver ?
Thank you :)
