Open TV app but also select channel within app as automation

Hi all, I’ve got an app on my LG smart tv which I frequently use to watch the ‘live TV’ version on, however upon opening the app when powering on the tv, i need to wait for it to load up then select down twice and select the ‘live TV’ channel.

Other than creating an automation (ie. power on TV > open app > wait 4 seconds to load up > ‘down’, > ‘down’ > select) would there be another way of doing this?
