Media keys sent to Spotify

Hey guys,
I've been using this app for quite a long time but never used some advanced stuff or played around with it much.
But one thing annoys me quite a lot in MacOS - media controls cannot be "forced" to control only Spotify.
Currently, I am not using any other player but I often have some chrome tabs open therefore I often end up in a situation where after pressing the Play button on my Mac keyboard I get the video in chrome going instead of my music in Spotify.

I obviously tried to google the solution and BTT is mentioned in a lot of results as solution.
Unfortunately am not able to "pull it off", I set it up like this


but this makes the Play Media key dead for good, unless I quit BTT app

What I did do wrong?
