Hello, the emacs-lsp-treemacs package does not bundle it's icons. This patch fixes the issue by copying the icons to `share/emacs-lsp-treemacs/icons` and patching the paths in `lsp-treemacs-themes.el`. This is the link to the issue in bug tracker: https://issues.guix.gnu.org/50329 Would you like to apply this patch? Thanks, Roman. This is my 2nd mail, because I forgot to set the subject in the previous.
