Can not enable mod_jibri_autostart to start record automatically

I am trying to enable mod_jibri_autostart.lua module with the help of this forum. mod_jibri_autostart.
But looks like not getting any log/hit in prosody logs.

Component "" "muc"
    modules_enabled = {

this is my jitsi-meet-cfg.lua file.

So is there any mistake?

Did you download the module and put it into /usr/share/jitsi-meet/prosody-plugins folder?

yes, it is there.
FYI, I am running from docker deployment. so, in docker-compose.yml file I have linked the prosody path to my /jitsi-meet/prosody-plugins.

No idea about Docker setup

If you use Docker then you need to set the env var for adding MUC modules to contain the new module.

Thank you saghul for pointing out. can you please give the file or what varname should I set in .env file?
