Howto change interface language from jitsi meet instance in Chrome browser under Windows

When I run Jitsi-meet with a Browser under Windows from how can I change the interface language?
Is there a parameter option to set it?
Without installing it, I don’t see the config files refered to here, but I don’t want to force my senior meeting partners to install a program and fiddle with a config file.
Is there any hope for us?

There is this for autodetection you can turn on/off on self-hosted deployment
or using the settings:

Thanks a bunch, I found it.

Hi @damencho
Can we change the language using iFrame API?
