Conference Mapper | Hosted Jitsi

Dear Team,
Hope you are doing well.

I am hosting Jitsi at my own server and everything is working great including Jigasi with successful inbound and outbound calling with asterisk server.

Can you please help me out with conference mapper settings.
I know aware that i have to use dialInConfCodeUrl in config.js but as explained in below article they are using Jitsi API for getting room info.
I want to know if i am hosting jitsi at my own server how to use this conference mapper. Please help.

best regards
Salman Ali

Just add it in your config, the same way it is added on
