Google Meet in Yosemite stopped working

iMac 24" Early 2009 with Yosemite.

I was able to Join Google Meet conversations until yesterday when I got "Your browser is not compatible with Meet". It is Chrome Version 87.0.4280.88 (Build oficial) (x86_64)

I also tried with Firefox 78.0.1 (64-bit) I've already installed.

Also dowloaded Edge but it is not supported in Yosemite.

What can I do apart of buying a new computer I don't need apart of this issue ;-)

Thanks
