Slow down animation framerate in Unity 2019?

I recently updated from unity 2018 to 2019, and I realized that there is no longer the option to change the framerate/speed (I don’t know what to call it) of an animation in the Animation tab. Where do I change it in the 2019 version?

I’m not on 2019 anymore for a performance issue, but if I can remember well there is a little menu in the top-right corner of animation tab, where you can make framerate visible

click on the gear icon or dotted icon at the top right of the animation window and check show sample rate https://i.imgur.com/n2DrQVu.png
