How to disable media keys in app?

Problem:

Discord is taking input from my play/pause keys. I want it to stop doing that.

I had at one point solved this, but I had to reinstall discord, it reset and I forgot what I originally did.

I have attempted to follow the suggestion from "JÄTTI" https://support.discord.com/hc/en-us/community/posts/360057093051-Disable-media-playback-with-media-keys?input_string=How%20to%20disable%20media%20keys%20for 

But I do not have a discord entry in my Run section.
