When Teams made an EDU branch, we lost accss to all sorts of stickers like Bummer Bert, I want to see a come back of these for "teacher" only channels, since some highschools will be using this software for communication among offices it would be nice to have the option of what sticker packs we'd like enabled so we can disable all the "kid friendly" ones and maybe add the "edgier" ones back from pre-split.
