get rid of custom emoji sticker...

[fisherking]

i added a dancing 3rd-party sticker to the emojis on my mac some years ago. i don't use it, but tiny images from it pop up when i bring up the emoji window (see red circled pics, below)

this only happens on my mac. and if i try to open the stickers window in messages, that window flashes then vanishes (so i can't get in to it to possibly remove the image).

any ideas? or does anyone know where this image is stored?

hovering over one of the icons shows me the file name, but 'find any file' cannot find anything with that name.

if i can find where these files are stored (am assuming a container?) i can delete...!
