sway application menu

[ClaudiaMS]

In the config file I find the following advice:
# Your preferred application launcher
# Note: pass the final command to swaymsg so that the resulting window can be opened
# on the original workspace that the command was run on.
set $menu /usr/bin/bemenu | bemenu | xargs swaymsg exec --

How do I have to add to get the application menu running?
