inkscape -w 48 -h 48 -o emblem-hash-verified.png --export-page=1 emblem-shield.svg  
inkscape -w 48 -h 48 -o emblem-hash-error.png --export-page=2 emblem-shield.svg

also

flatpak run org.inkscape.Inkscape -w 48 -h 48 -o emblem-hash-verified.png --export-page=1 emblem-shield.svg  
flatpak run org.inkscape.Inkscape -w 48 -h 48 -o emblem-hash-error.png --export-page=2 emblem-shield.svg

After modifying the icon, run the install.sh script again to update the installation.
