LAST-N configuration

Hi all, and thank you very much for this excellent product.

I googled a lot, and searched this community but couldn’t find an answer to my question(s):

How to configure LAST-N parameter, if possible, at server level? Is there any other way to configure it?

Thanks in advance
Aldo

I try to answer to myself.

I’ve found “config.js” in “/usr/share/jitsi-meet-web-config” folder, it contains a “channelLastN: -1” statement. Should I modify this one to set “last-n” parameter at server-level?

Moreover, I’ve read somewhere that LAST-N has an “adaptive mode”, what does it mean?

Kind regards
Aldo

I’d love an answer to this as well
