Note the remindme bot uses an allowlist and this community isnt in it, youd have to get your community mods to request it gets added in the repository if you want to use it here
Bot guidelines for some of the major instances dont allow bot posting unless its been approved by a mod. Also makes more sense for mods to choose what bots to allow in their community rather than response bots being fully allowed everywhere since that can easily get out of hand if a bunch get made
