geforce now "streaming games is not supported in this browser"

[fenopa]

play.geforcenow.com says "streaming games is not supported in this browser" although it doesn't say that on official chrome version and works fine. it doesn't look like it's about user agents, you use chrome user agent anyway.

I checked headers, "SEC-CH-UA" has a difference between google chrome and chromium, that could be the reason.

I tested it with both 109 and 122 versions (I'm using thorium-win7 but it should be same for all os), thorium versions don't work but official chrome 109 works.

Could it be possible to make it see the thorium as chrome and don't say not supported browser? changing SEC-CH-UA would probably do the trick?

well I played with headers with some extensions and it doesn't look like it checks from headers. so what makes it say "not supported in this browser"? how can I make it work? is there anyone who can use geforce now with thorium?

looks like same as this: https://community.brave.com/t/geforce-now-unplayable-on-brave/524308/4

how they detect it's not chrome or edge without user agents? how would it possible to make them see the browser as chrome?

FYI I found this issue while looking for the same problem with Brave. They are calling the window.speechSynthesis.getVoices() method and checking if any of the voiceURIs contain "Google".
