I'm using greetd 0.10.3 on nixos-unstable. For a few weeks, my wayland 
window managers crash when i run them like this (NixOS [1]):

   services.greetd = {
     enable = true;
     settings = {
       initial_session = {
         # command = "${pkgs.bashInteractive}/bin/bash -c 'sleep 3 && 
hyprland'";
         command = "${pkgs.hyprland}/bin/hyprland";
         user = "sperber";
       };
       default_session = {
         command = ''${pkgs.greetd.tuigreet}/bin/tuigreet --user-menu'';

I would like to bind "mark as read" and "move to Trash" to the same key 
so that they are executed on a message one after the other.

How do i do that?
