Bixby Routine Folded

[Bonsaibo]

I created a routine that when completely folded and the phone is ringing, to run a quick command in which I must say "pick up phone" and then run the preset "answer this call". However, Bixby quickly listens (like 1 second) for the verbal input, but whether I say something or not, it just answers the phone. I thought it would wait until it received the words "pick up phone" but doesn't. Any thoughts?
