Debian chromium package enable_hangout_services_extension=false by default. How to turn it on during run time?

[Robbi Nespu <robbinespu@gmail.com>]

Hello! I not able to use "screen share" on google meet using chromium 
browser.

Each time I clicked on it, I get "your browser can't share your screen" 
and dev tool > console don't complaint anything about it.

I did a google-fu and found out it related with a feature that been 
disabled by debian (rule) during built.

$ apt-cache policy chromium
chromium:
  Installed: 89.0.4389.114-1
  Candidate: 89.0.4389.114-1
  Version table:
 *** 89.0.4389.114-1 500
        500 http://ftp.jp.debian.org/debian bullseye/main amd64 Packages
        100 /var/lib/dpkg/status

So I checked here 
https://sources.debian.org/src/chromium/89.0.4389.114-1/debian/rules/
# disabled features
defines+=is_debug=false \

         use_libjpeg_turbo=true \

         use_unofficial_version_number=false \
         enable_vr=false \
         enable_nacl=false \
         enable_nacl_nonsfi=false \
         enable_swiftshader=false \
         enable_reading_list=false \
         enable_one_click_signin=false \
         enable_iterator_debugging=false \
         enable_hangout_services_extension=false \ # <----------- HERE
         optimize_webui=false \
         angle_has_histograms=false \
         enable_js_type_check=false \
         treat_warnings_as_errors=false \

How I can turn it on during runtime? without need to patch manually and 
built the package locally?
