Alexa command to stream on Roku

I have an Echo Dot and a Roku TV and am trying to make a routine. I can get the Echo Dot to turn on the tv and launch a streaming service but I cannot get it to open a streaming service that I have to select a profile on (Netflix, Hulu, etc.) it just stays on the “choose a profile” screen. And I can’t get it to play anything, it just searches. For instance “Echo play Game of Thrones” has her search the Roku for GOT and not actually stream it. Is there a solution to this?
