How to modify jitsi-meet.cfg.lua (Docker)

I tried the following:
Modified file:~/.jitsi-meet-cfg/prosody/config/conf.d/jitsi-meet.cfg.lua ,add following properties
smacks_max_unacked_stanzas = 5;
smacks_hibernation_time = 60;
smacks_max_hibernated_sessions = 1;
smacks_max_old_sessions = 1;
But when I restarted the container, the configuration was changed back.
How to keep the changes?
Thanks!
