How do I properly delete Facebook and instagram accounts? - Lemmy.world

During this Threads craze, I’ve decided to delete my Facebook and instagram personal accounts. How should I go about this? I know both social networks provide this feature but I can’t stop thinking about Discord, where any message you sent stays there if you don’t erase it manually before deleting your account. With this in mind, what can I do in order to minimize the amount of data left behind on Facebook and instagram? P.S. I’ve tried looking for similar posts using some keywords, but I couldn’t find anything in this community. Sorry if this has been asked before.
