It works with xelatex but to find texlive fonts by font name xetex
needs the font directories to be added to the fontconfig configuration
texlive supplies a fontconfig file for that purpose installed at
/usr/local/texlive/2021/texmf-var/fonts/conf/texlive-fontconfig.conf
or equivalent place but it is not added to the fontconfig by default
you need to do that post install

it contains

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <dir>/usr/local/texlive/2021/texmf-dist/fonts/opentype</dir>
  <dir>/usr/local/texlive/2021/texmf-dist/fonts/truetype</dir>
  <dir>/usr/local/texlive/2021/texmf-dist/fonts/type1</dir>
</fontconfig>

(although I'd recommend not including the type1 line)


see section 3.4.4 of the texlive manual.
