Suggestion Editing/Deleting DMs even after a long time

[otome!]

It'd be cool to at least make a kind of DM section where there isnt a time limit to editing or deleting a message. Sometimes people can take a few days or more before answering and the content of the message is already not up to date so itd be cool to be able to delete it all together, like anyone would do on pretty much any other messaging platform. Thanks^^

I think there's a one day or two days limit right now which clearly isnt sufficient in my opinion
