TCL/Roku automation question

Third party integrations
1

I would like to turn on the TCL TV, select Netflix, and select (via Enter) the user. Turning on the TV works by itself but how to select Netflix and then hit Enter (possibly followed by other key entry)?

I have this simple action which does not work:

service: media_player.select_source
target:
   entity_id: media_player.43_tcl_roku_tv
data:
   source: "Netflix"

This results in Message malformed: Integration " not found

2 
service: media_player.select_source
target:
  entity_id: media_player.ricky_roku
data:
  source: Netflix

worked for me. Only difference I see is the quotes around Netflix.

Thanks. Maybe that was it. It works now. If I want to follow this with a few commands, I presume that would be a separate action using the Remote:Send Command service. (This is part of an automation). The UI says: “Sends commands or a list of commands to a device”. If one uses the GUI, how to specify a list of commands?
