Getting actual member List

[Ralf-Os]

Hi,
how can I grab an actual member list of a group? It seems, only groupSysMessage sends member lists. But that is only fired on joining a group with the bot.
My problem is to keep track of members in my database, I often get old entrys that are no longer in the group.

Hello! Just letting you know that publicly answering this question in detail would encourage thot bots that could post mass advertisements (as is discussed here), so you may not get a clear answer to this question here. Best of luck to you!
