.desktop files are created for Thorium itself and content-shell (named thorium-shell), with theses cmdline flags being appended to both via the wrapper file > '--no-default-browser-check --use-gl=desktop --enable-experimental-web-platform-features --new-canvas-2d-api --show-component-extension-options --autoplay-policy=user-gesture-required --enable-features=VaapiVideoDecoder,PageInfoAboutThisSite,ParallelDownloading,ChromeLabs'.

There are also additional desktop actions: when right clicking the Thorium launcher it gives three additional desktop actions, one to open thorium-shell, another to open in Safe Mode which disables any flags one has set in chrome://flags until the next launch, and lastly to open in Dark Mode which appends the --force-dark-mode flag.

The Thorium .desktop file and content-shell .desktop file have flags added for experimental and useful features, namely: Disabling the Default Browser check and InfoBar, Experimental web platform features, Experimental Canvas2D, showing component extensions on chrome://extensions, requiring a user gesture to initiate playback of media, VAAPI Video decoder, Page Info v2, and Parallel Downloading. The --enable-clear-hevc-for-testing in thorium-shell enables testing H.265 (but still won't demux it).
