Customize welcome page problem

Hi,
I installed jitsi on my server (quick way). I would like to modify the welcome page. I tried to use dirty short cut by editing /usr/share/jitsi-meet/libs/app.bundle.min.js file. But I can not see in this file any content as on the screen (i.e. “Secure, fully”). Is this normal? Maybe i should edit another file?
Regards,
Pawel

Don’t forget the localizations in /usr/share/jitsi-meet/lang/

It works. Thanks a lot!

What do you mean with “Don’t forget the localizations”?

I don’t really see what’s unclear about my reply - most text in Jitsi’s interface comes from the language localization files and not from app.bundle.min.js.
