Need a tamper monkey script for an online io browser game.

I’m looking to get a script for an io game called “mope.io” So when i reach above the tier that I want to get a rare animal from and then die a panel will show up with different animals a tier below from where I died and I wanted the script to be able to reset the panel by pressing the up key, so I’d be able to get rare animals of my choice. I have a video of the type of script that someone made about 9 months ago but since then the ui has changed for choosing animals.
