ok so in #calckey we currently offer the option between 3 default reactions, next to the reaction menu, you can select the quick reaction to be either a ⭐a 👍or a ❤️, lets call it the "quick reaction" for now, I kinda wanna give instance admins the chance to set this to any reaction of their liking, buuut, we set a icon for this in the interaction menu, see the picture, and I dont know of a way how to generate a icon like this for every emoji, even custom ones, soo, I need thoughts on this, any help apprechiated 
fuchsiaaaaaaaaaaaaaaaaa
@cleo you might be able to do something with CSS filters, like using the emoji image with a `filter: contrast(0)` turns it into a grayscale filled version, if you get real fancy with it you could place the custom emoji on top of itself with a little scale factor too, in different colors, to get an outline + fill
