Invoking URLView from a Tmux command

[snoblenet]

Does this create a Tmux command that I can send to Tmux from elsewhere?

I tried prefix:urlview and prefix:urlview-key.

I ask because I'd like to bind this to ⌘-u in Alacritty with something like this:

 - { key: E, mods: Command, command: { program: "/usr/local/bin/tmux", args: ["urlview-key"] } }

Similar to my existing bindings, which are like:

 - { key: K, mods: Command, { program: "/usr/local/bin/tmux", args: ["clear-history"] } }
