Tac x app compatibility with Garmin connect

I pay a subscription to Tac x. However the training program offered on connect is better - why doesn’t it upload on the Tac x app so I can use it?

the program does go to my Garmin Edge, but when I start it wants me to pick a route - when working on HR guided training runs I don’t necessarily want a route to follow - how can I use it without this?
