Changes in lib-jitsi-meet.min.map are not applied in browser

Replaced code

return this._connect(jid, password);

with

return this._connect(jid, 'hello password');

in lib-jitsi-meet.min.map, then reloaded the page and the file was loaded successfully. (see the image below)

But when debugging with chome browser, nothing is changed, the password parameter of _connect function is undefined while “hello password” is explicitly passed to the function.
This behavior is seen whole over the code. Nothing is applied anywhere although the code is changed and browser has downloaded newer version of bundle.
Anyone can help?
thanks

That is the source code map file, it doesn’t get executed. You need to modify the real JS file.
