How to have chromium appear as chrome to web sites?

I would like to use skype on an old netbook with a 32bit-only atom processor (N270).

The skype linux client is only available for 64 bit linuxes. But they have a web app. However, their web app is only supported for the browsers "Edge" and "Chrome".

Edge is a windows browser and does not run on linux. Chrome is no longer available for 32 bit linux. But Chromium is. As far as I understand, Chromium is the same as Chrome except for some additional Google integration.

Skype web service actually starts with Chromium and lets me log into my account, I get much farther with it than with Firefox, which is immediately blocked by Skype web. However, I cannot participate in audio and video calls with chromium, the buttons for initiating them are greyed out, and a tool-tip says "Audio and video calls are not supported on your browser."

My question is can I make Chromium more appear like Chrome to circumvent this not-Chrome detection and hopefully use Skype on this otherwise unused old netbook (The processor is an Atom N270 and does not support 64bits).
