As it says. AUR pkg google-earth-pro 7.3.6.10201-2 has a requirement for libxml2-legacy. The latter is available in Arch repo, extra.
I can confirm that google-earth-pro works if the Arch pkg is used.
Package libxml2-leagcy was added to omniverse some time ago ;-)

I'm never sure which of the optional repositories to use. The wiki has an example with Arch extra. As I have an arch system as well I can just pacman -U the Arch zst without editing pacman.conf.
