Hello Frankdux,
I'm not sure, if it wouldn't work since Linux Mint is based on Ubuntu and Ubuntu is one of the supported systems. Really important is, that you use an actual chrome based browser. In the Mint forum there's a thread: https://forums.linuxmint.com/viewtopic.php?f=58&p=2245303
For me the best way to install GOS on my Pixel 6 was using instead a computer a second smartphone and vanadium as a browser. Just connect the devices with the original usb c cable and go on.
