Unable to change the default avatar

Hello everyone,
I have integrated Jetsi directly in my React app using the API (Without a self-hosted server).
I have been trying to find a way to change the default avatar when the user camera is off.
I found this discussion where it’s mentioned I should use

And I added it like this:

            RANDOM_AVATAR_URL_SUFFIX: ".jpg",
          onJitsi={() => console.log("Meeting has started")}

But, this had no effect.
Any idea what’s going on?

Those settings no longer exist. You can now overwrite the Gravatar-equivalent server URL. Check Configuration | Jitsi Meet
