Sadly it still doesn't work on my side with just 'chrome' or
'ENABLE_WASM=1 chrome' on the command line.

I agree.  The only reason why I did this is because this line is found
in /etc/firefox-esr/unveil.main.

I am grateful for your help.

I am beginning to think that this issue may not be related to iridium
or chromium because other browsers on my system fail to access the
webcam, such as qutebrowser or otter-browser, while firefox always
succeeds.

There must be a common link between those browsers.  Could this come
from some package that would be required?  But which one?
