i do have a question, sure
for the avoidance of doubt, you are saying that a matrix bridge can copy all previous messages over from a discord server, to a matrix server, even the messages made before the creation of the bridge? i.e, transfer the entire conversation log over to the matrix server, going back all the way to the first message in a channel?
actually, phrasing this another way, i just caught myself in the XY problem. what i need really, is a copy of a given discord server's content, onto a fresh matrix server. bridge or no bridge. is there any way to (broadly) copy and paste the content of a discord channel over to a matrix server, one time only. i know how to extract the discord content using the discord chat log tool, tokens etc. so, say i have one of those html files with the full chatlog and contents - how do i put that into a matrix server, and have it roughly readable? (if that's possible)
thank you for your patience, i have tried search engines for months with no clear answers
